After a week of too little sleep, I slept about 12 hours last night to "catch up". It made me wonder: what is happening physically that signals that I'm done sleeping, or conversely, that I need to sleep. I read this question and its answers, which explain how brain waves indicate different sleep stages: Why sleep? No, actually, why wake?

But what causes the changes in these brain waves? I'm curious about the mechanism by which my body determines that it needs sleep, and not just a set amount, but a specific amount based on my previous week's lack of sleep. is it something in my brain or is it a hormone or something else?


During sleep the cerebrospinal fluid clears out the waste products of brains cells. Sleep fragmentation or sleep deprivation can prevent this process, or reduce its efficiency. So I think the accumulation of waste products cause that you have to sleep more after sleep deprivation and extreme sleep deprivation (e.g. by fatal insomnia) can cause death. Low quality sleep and sleep deprivation can cause or worsen both neural (e.g. Alzheimer's disease), and metabolic diseases (e.g. diabetes mellitus, etc… ), so you should avoid it, if you can (I cannot :D).

Daily sleep is regulated by the circadian clock. Many hormones can affect that clock, e.g. melatonin (dependent on blue light), insulin, etc…

The conservation of sleep across all animal species suggests that sleep serves a vital function. We here report that sleep has a critical function in ensuring metabolic homeostasis. Using real-time assessments of tetramethylammonium diffusion and two-photon imaging in live mice, we show that natural sleep or anesthesia are associated with a 60% increase in the interstitial space, resulting in a striking increase in convective exchange of cerebrospinal fluid with interstitial fluid. In turn, convective fluxes of interstitial fluid increased the rate of β-amyloid clearance during sleep. Thus, the restorative function of sleep may be a consequence of the enhanced removal of potentially neurotoxic waste products that accumulate in the awake central nervous system.

According to the traditional understanding of cerebrospinal fluid (CSF) physiology, the majority of CSF is produced by the choroid plexus, circulates through the ventricles, the cisterns, and the subarachnoid space to be absorbed into the blood by the arachnoid villi. This review surveys key developments leading to the traditional concept. Challenging this concept are novel insights utilizing molecular and cellular biology as well as neuroimaging, which indicate that CSF physiology may be much more complex than previously believed. The CSF circulation comprises not only a directed flow of CSF, but in addition a pulsatile to and fro movement throughout the entire brain with local fluid exchange between blood, interstitial fluid, and CSF. Astrocytes, aquaporins, and other membrane transporters are key elements in brain water and CSF homeostasis. A continuous bidirectional fluid exchange at the blood brain barrier produces flow rates, which exceed the choroidal CSF production rate by far. The CSF circulation around blood vessels penetrating from the subarachnoid space into the Virchow Robin spaces provides both a drainage pathway for the clearance of waste molecules from the brain and a site for the interaction of the systemic immune system with that of the brain. Important physiological functions, for example the regeneration of the brain during sleep, may depend on CSF circulation.

Sleep fragmentation is present in numerous sleep pathologies and constitutes a major feature of patients with obstructive sleep apnea. A prevalence of metabolic syndrome, diabetes and obesity has been shown to be associated to obstructive sleep apnea. While sleep fragmentation has been shown to impact sleep homeostasis, its specific effects on metabolic variables are only beginning to emerge. In this context, it is important to develop realistic animal models that would account for chronic metabolic effects of sleep fragmentation. We developed a 14-day model of instrumental sleep fragmentation in mice, and show an impact on both brain-specific and general metabolism. We first report that sleep fragmentation increases food intake without affecting body weight. This imbalance was accompanied by the inability to adequately decrease brain temperature during fragmented sleep. In addition, we report that sleep-fragmented mice develop glucose intolerance. We also observe that sleep fragmentation slightly increases the circadian peak level of glucocorticoids, a factor that may be involved in the observed metabolic effects. Our results confirm that poor-quality sleep with sustained sleep fragmentation has similar effects on general metabolism as actual sleep loss. Altogether, these results strongly suggest that sleep fragmentation is an aggravating factor for the development of metabolic dysfunctions that may be relevant for sleep disorders such as obstructive sleep apnea.

Inadequate sleep simultaneously modulates the levels of multiple hormones that govern metabolism, In general, with sleep deprivation, the following hormones are decreased: insulin, growth hormone (GH), growth hormone releasing hormone (GHRH), and leptin levels. In contrast, ghrelin and somatostatin are increased. Essentially, hormones that signal that the body has plenty of energy are decreased, while those that signal energy need are increased. Experiments utilizing knockout animals as well as pharmacological agonists, antagonists, and immunodepletion of the proteins, illustrate that these hormones affect sleep regulation. Diabetic rats have decreased sleep time and consolidation while replacement of insulin increases increases slow-wave sleep.

In humans, melatonin is produced by the pineal gland, a small endocrine gland[26] located in the center of the brain but outside the blood-brain barrier. The melatonin signal forms part of the system that regulates the sleep-wake cycle by chemically causing drowsiness and lowering the body temperature, but it is the central nervous system (specifically the suprachiasmatic nuclei, or SCN)[26] that controls the daily cycle in most components of the paracrine and endocrine systems[27][28] rather than the melatonin signal (as was once postulated).


Let's Talk About Sleep Paralysis: When You Wake Up and Can't Move

Do you ever wake from sleep and realize you can’t move your arms or legs, lift your head, or wiggle your fingers or toes? You're aware of your surroundings, but you can't move or speak. You might even see weird visions or hear strange sounds.

This is called sleep paralysis, and it occurs when part of the brain is awake, but the parts controlling your body are still asleep—so when you try to move, you’re unable to for several seconds or even a few minutes. Episodes can be broken by either waking up fully or falling back to sleep. Either way, it can be extremely frightening.

A healthy patient of mine had been sleeping poorly for a few weeks. Her wake-up times varied over several hours and she was getting just five hours of sleep overall each night. She was tired during the day, but a cup of coffee (or three) mostly compensated for that.

Sounds pretty routine, right? But then something scary happened. She told me that one morning, she woke up from sleep but felt like she couldn’t move or breathe. She was aware of her surroundings, but when she tried to move her head or arms, nothing happened. She felt a building sense of impending doom and panic. Scared, she tried to scream for help but no sound came out. Her bed partner moved, and all of a sudden, she regained the ability to move. After a few minutes, everything felt normal.

I’ve been a sleep physician for several years now, so after listening to her and learning more about her health history, I realized that she’d experienced an episode of isolated sleep paralysis—meaning she didn’t have any other sleep-related conditions. This was actually good news, as sleep paralysis is a safe (though certainly scary) condition in isolation.

It’s also pretty common. A systematic review published in the journal Sleep Medicine Reviews in 2012 found that 7.6 percent of the general population has experienced sleep paralysis at least once. According to a review from Brian A. Sharpless, Ph.D., a clinical psychologist, professor of psychopathology at the American School of Professional Psychology, and author of Sleep Paralysis: Historical, Psychological, and Medical Perspectives, women are more commonly affected than men, and those with existing anxiety disorders are more at risk than the general population.

There are two parts of the brain thought to be central to sleep paralysis: the parietal lobe and the temporal lobe. With a little misfiring in these lobes, your brain wakes up but your body stays asleep—so when you try to move, your body doesn’t listen.

You can think of the brain as hundreds of light bulbs, each connected to an on/off sleep switch. In a perfect world, when the brain transitions from sleep, all of the switches would be triggered at once, so the entire brain would wake up as a unit. Sometimes, however, some switches are triggered early while the rest of the brain is trying to catch up. When awareness wakes before your limbs, sleep paralysis occurs. (In the same method, sleep walking can occur if your legs wake before awareness. Think along the same lines for sleep talking, as well).

Usually sleep paralysis happens when waking up, rather than falling asleep. This is what my patient had, and it’s the most common kind, according to a 2012 review published in the journal Physiological Reviews. The other type occurs as you fall asleep, when the parts of the brain responsible for moving the body fall asleep before the parts responsible for awareness.

Sleep paralysis can happen to people with other sleep-related conditions like narcolepsy, sleep apnea, and idiopathic hypersomnia (extreme sleepiness), according to the Mayo Clinic, but people without these conditions can also have it. Having it by itself, like my patient did, is called “isolated” sleep paralysis.

A report in the journal Consciousness and Cognition reported three common types of hallucinations among sleep paralysis sufferers: "intruder," or the feeling that someone or something is in the room with you "incubus," or the feeling that something is sitting on your chest and "unusual bodily experiences," or the feeling of flying or floating.

I’ve treated patients who became so afraid to fall asleep that they avoided sleep as much as possible. They would try to stay up late to minimize sleep time. This lead to sleep deprivation, which by itself, can make sleep paralysis more frequent, according to the American Academy of Sleep Medicine.

Several factors can make the condition worse, such as irregular sleep patterns (like jet lag or sleeping much later on weekends than you do during the week), not getting enough sleep, and drinking alcohol. To minimize sleep paralysis, aim for seven to nine hours of sleep each night, try to wake up and go to sleep around the same time every day, and take time to properly wind down before bed at night.

In severe cases, your doctor might recommend an antidepressant medication, which affects the release and re-uptake of neurotransmitters that form the signals between neurons in the brain. Antidepressants aren’t officially approved by the FDA for sleep paralysis, but they may reduce the frequency of attacks in some cases, according to Dr. Sharpless.

That's what makes it so terrifying. Baland Jalal, a researcher in Cambridge University's department of psychiatry, recently proposed a meditation-based approach in Frontiers in Psychology. His four-step approach includes the following:

  1. Tell yourself that sleep paralysis is common, benign, and temporary.
  2. Remind yourself that there's no reason to be afraid.
  3. Focus on something besides the paralysis, like a happy vision or mantra.
  4. Try to relax your body and avoid moving until the episode has passed.

While scary, these episodes are harmless and typically a sign of poor sleep quality. If you've tried the strategies above and you're still experiencing sleep paralysis, then it's time to visit your doctor. They'll review your sleep habits and see if there’s anything else they can do to help.

Nitun Verma, M.D. is a sleep medicine physician trained at Stanford University. He's a spokesperson for the American Academy of Sleep Medicine and practices at Crossover Health in the San Francisco Bay Area.

Ticklish sensations

Question:Sometimes when I meditate I get a really ticklish sensation in my heart area. It simultaneously makes me want to laugh but there is also sense of anxiety or fear attached to it. If I keep sitting, I just feel like my heart has opened up and I feel a part of me is very vulnerable or scared, but at the same time another part of me feels very soothed. What could this mean?

Deepak:One can have almost any type of physical sensation during meditation in any area of the body. Because the mind and body are so closely connected, when the mind experiences more expansion in meditation, the body gains a deep enough state of rest to normalize any imbalances that may be stored in the body. The ticklish sensation in your heart just means that some normalization is occurring there, allowing for a more full expression of your emotions. The sense of anxiety or fear is a by-product of that clearing process. Don’t give these sensations and feelings too much importance. It is a valuable process, but don’t focus on it simply return to the meditation process.


What Anxiety Does to Your Body: 7 Common Physical Symptoms

While conversations on anxiety tend to revolve around how a person feels mentally and emotionally, it’s important to consider the physical symptoms, too. For a lot of women struggling with anxiety, it’s not always clear how to make the connection between how they are feeling physically and their emotional state.

To begin to understand the physical symptoms of anxiety, it’s important to remember how anxiety triggers the physical “fight or flight” response. While a helpful tool when facing a real physical threat, your brain doesn’t distinguish between that and anxiety, which is often caused by fear and worry. Because your brain is wired to respond to any perceived threat by kicking on your sympathetic nervous system, when you feel anxious a lot of involuntary responses start to happen, like increased breathing and a more rapid release of hormones into your bloodstream.

How your body physically responds to anxiety is unique, but there are seven common physical symptoms that you should be aware of. When you understand what your body does when it’s stressed, you can start to connect the dots between your anxiety and your physical body.

  1. Racing heart. When your brain receives stress signals, it triggers your adrenal glands to produce adrenaline and cortisol. As these hormones are released, your heart responds by speeding up your heartbeat, which explains your racing heart.
  2. Shortness of breath. When your body is stressed, it responds by providing you with more oxygen so that your body can receive more blood. This increase in oxygen can actually start to do the opposite of what you might expect, causing you to breathe rapidly and even hyperventilate.
  3. Chronic exhaustion. Because your body produces stress hormones when you’re anxious, your body ends up staying in a constant state of high alert. To keep your body operating at this high-stress level is draining – and makes you feel exhausted more often than not.
  4. Poor sleep. Whether you have difficulty falling asleep, staying asleep, or just wake up feeling anything but rested, anxiety plays a big role in the quality of sleep you get on a regular basis. One explanation for this is the fact that you can’t stop your thoughts from racing when you’re feeling anxious, which can get in the way of a good’s night sleep. Another explanation is that those stress hormones (cortisol and adrenaline) keep your body from resting.
  5. Achy muscles. The fight or flight stress response causes your muscles to tense up and, when you’re in a constant state of stress and anxiety, it doesn’t give them an opportunity to relax. As you can imagine, chronic tension in your muscles leads to persistent discomfort.
  6. Stomach discomfort. Anxiety is directly linked to your GI system. The more anxious you feel, the more likely you’ll experience pains in your stomach, constipation, diarrhea and other GI issues.
  7. Poor immunity. If you find yourself catching a lot of colds or coming down with a virus more often than you used to, there’s a good chance it can be attributed to your levels of anxiety. Because it’s difficult for your body to function when it’s constantly in the fight or flight response, your immune system suffers.

Finding ways to manage and reduce your anxiety will improve how you feel, physically and emotionally. By connecting your physical symptoms to your anxiety, you can better understand the toll it’s taking on your body – and find the motivation you need to make healthy changes to your current lifestyle.


Why Do Spiritual Awakenings Happen?

So, why do spiritual awakenings happen in the first place?

Spiritual awakenings happen as a natural product of your Soul evolving, expanding, and maturing. Just as everything in life grows, so too does our connection with our Souls.

The more you connect to your Soul (whether accidentally or intentionally), the more you experience transformation. The more you come to embody your Soul, the more you taste true and lasting joy, peace, fulfillment, freedom, and love.

While the spiritual awakening process can feel painful and disturbing at first, it ultimately helps you to live a more meaningful life. The sensation that your life doesn’t make sense anymore is the product of having all of your former beliefs, desires, and paradigms challenged and often disproven. This is traumatic, but a necessary part of your expansion.

Sleep Paralysis

Years ago I was on a fishing holiday in France but had to return to the house due to the thunder storm outside. Once i got in the house, watched a bit of telly then set up to sleep on the sofa. everyone else was in the bedrooms.
Cant describe it but as I was laying there i felt like i was awake, just really tired. I heard the front door slowly squeek open, then it shut, for what seemed like a second nothing happened, but by then i was petrified and couldnt move, waited a sec then these footsteps came slowly over to me on the floor like a lady in high heels was the sound, this completly ruined me! I couldnt move, but didnt really want to, I was laying with my back towards the door and as the steps came closer i felt like my heart was pounding so hard it was shaking my whole body, plus i could hear it pounding! Then the steps stopped, but they came so close i could feel this person standing right over me, I was frozen with fear. Then to make things worse, this f.cker put its hands round my neck and shook me softly like a lympt attempt at strangling me. i still couldnt move nor did i want to. it stopped and this person walked off slowly and shut the door behind them.
I didnt move until the morning, not sure how long this was as i stayed in tha same position the whole time swetting like a pig completly awake!! i got up slowly and the sofa was soaked with swett, i am talking puddles like!!
i did not mention this to anyone else until a few weeks later back at home as i was worried they would think i was a nutter and also didnt want to scare anyone on the holiday.

Anyway, i have had similiar things happen throughout my life, mainly as a child. One i had of a youngster was i was being drilled in the stomache by a kango concrete machine and as i came around my whole body was shaking like it was vibrating! Also one of someone grabbing my feet and yanking me down the sofa!

What is it with me and sofas.

Anyway, I am glad i have come across this site as i think the ones i had as a child and the odd ones i get now are just this sleep paralysis like recently opening my eyes up and a massive spider and its web right next to my face. i couldnt move but when i could i smacked the web and hid under the covers. but when i got out there was nothing there!
I can take these ones as slepp paralysis but the france experience is something that was terribly real feeling!! so and i am not convinced either way on that event.

Im scared

Hi my name is lexie im 14 years of age this morning i decided to look up what was wrong with me this morning i was awake and its was like i couldnt control my body i could move open my eyes like i was paralyzed i was scared out of my life this is the first time this ever happed to me i dont wanna die and i hope i dont i could not breath i could here because hanna montana was on in scared out of my life and what i do is i force my self to move but i cant but in a few secounds later i will see and be back to my normal self can any one help me?

Only outlet ill get

I kind of broke down the first time I read this, ive been having these "dreams" my whole life. I never told a soul because once when i was a kid i was describing it to my mother and she looked at me with such fright that i passed it off to her afterwards as a bad dream. After all no fault of hers she didnt know but when your mother looks at you like your odd you never mention it to anyone else, so ive lived my life thinking im a normal kid who is secretly haunted by demons. Kind of obsurd to write but i didnt know what else to think.
My demons have always been the same looking, they act differently but it usuely follows the same pattern. I usually awake on my back, occasionally on the side but usually on the back, then in the corner of the room at the foot side of my bed the creature is standing there. Sometimes i can see him sometimes hes just below my eyesight and im aware of him sometimes he hisses or breathes but i am always paralyzed at this point. It then falls down into a crawl position and i can hear it/sense it move up to just below the side of my bed. Ive never had it touch me but ive had it right in my ear hissin but its favourite is laying right next to me on the ground. I dont think i need to describe the terror that is involved in these situations, once my paralasyis wears off my biggest challenge is rolling over looking on the floor to see its not there. best way to describe him would be like that creature from the black lagoon movie a long time ago, but without the fish gills, more smooth cause its not a suite, and not as bulky.
Ive never written or spoken that, i cant stop reading ppls comments, im 25 and this article literally changed my life. Im not alone

Sleep Paralysis and Dark Entity

I've had sleep paralysis every so often since I was twelve or thirteen (currently 26). At least, that's the first time I can clearly remember trying to open my eyes, and move my limbs and it not working. But I only recently, within the last two years, even thought of looking into it and discussing it with my family. But I've never experienced the dark or ominous spirit that people speak of until just now, and it's horrible! Only, in this instance, I was dreaming of sleep paralysis, and the entity was coming towards me. It was quite disturbing and I'm keen to never experience this again. Does this shift in the phenomenon's properties have any meaning?

This is crazy stuff!

Hey im not actually sure whats wrong with me it seems to be a mix of spiritual and this SP. the reason why im saying this is that the first time i ever experienced this was when i was driving home i kept on feeling like i was being followed by something every time i got near my house. then weeks of this happening i experienced the first time (over a year ago now) and i woke up during the night and i saw my friend sitting on the bed and asked me to follow him to the kitchen. i didnt because i questioned why he was there (in my head) cuase by then i could move. but then wen he left the room and i didnt follow i couldnt move and cudnt call out to my mom and dad (as i tried to scream)struggled to breathe. it has happened ever since.

but its different everytime once i heard someone in the garrage walking and then came in my room and i sat up saw the door move and a human figure was standing there and i put my fists up cause i thought it was someone. but then it jus faded away afta about 5 seconds. then somenights i just cant move and it seem like the SP with most symtoms from it. iv been also been sleeping next to people when ill wake up and feel something near me and swing for it until i realise nothing there. neally knocked my friends teeth out was pretty funny now that i think of it.

or ill wake up know im awake and the room just then gets darker and il be like "ahh here we go again" and then everything over again. few times this feeling has happened and when i snap out i seriously felt like crying. because i jus wanted it to stop. but whenver it happens i pray to jesus and it does go away (and im not the biggest christain out their thats for sure)

but the weird thing is every night it happens i get that weird feeling randomly during the day like sumthing is watching me and thrills just go up my body and i get paranoid. that happened again last night. but last night was different because my friend messaged me late at night wen i went to bed but i was going to read it in the morning and then half hour later ( i hadnt fallen asleep by then) but the room jus got bright as if my fone lit up then i looked and it was dark. closed my eyes (played with the feeling that was happening to see what could happen) and then i started feeling tingly in my body (more then the usaul when you get this) and i got dizzy and then again the room looked really bright but was from another angle. (which was extremely different to other experiences)

and i no im not hallucinating because i know by my own eyes what is happening because im paraniod about looking like an idiot. so im not to sure what is wrong whether its spiritual or SP or both :S
jus thought id let my story out

I'v seen it's true form

I'v been a slave to this sp for some time now and to be honest i think it is a deamonic force. Ive wokein up to my hands being heald above my head and something screaming in my ear but it did not sound human. I'v tried sleeping in the living room, from what I can remember I was being pulled off the couch, I was able to fight back. I'v had dreams to where it would take on apperences of my loved one's but it's eyes remaind red on that occasion I was able to fight it back I'v punched it's head at least three times but it still over powered me in my dream. it was at that point that I was able to find a painting of the last supper that has a light above it and I hung it on my bedroom wall. When i woke up the window was open the picture tilted to the side and the light was flickering mind you this was during winter so I closed the window then I just went back to sleep. And then this might shock you I went to sleep one night in my dream on command I was able to picture my self in a room with one matress lying on the floor I look over I can see a closet that was black and i was unable to see what was inside so I decided I'm not playing his game no more Im going to start mine, so then I said I command you to come out you BITCH. He finnaly showed him self he was all black with red eye's big sharp fang like teeth and abnormaly tall I'd say 7 foot he ran after right from the closet and picked me up slammed me into a wall and said in a very deep very dark voice. what do you want. so i told him I WANT YOU GONE he said no so then i said FUCK you. And then at that point he let go and then I woke up. The whole time my wife was watching and listning to me she said i was shaking she also said I was growning angree and mean like. So Tonight I'm going to call him out tonight while having on a cross and this time I am going to fight him back I think out of all these years He has had no one confront him before and then I came along he's about to get that beat down becuase I am not afraid mabe that's why I'm able to hit him. WISH ME LUCK

Sleep Paralysis

I've tried to fight back with that entity.It worked so i thought but then it came back i've learned to embrace it sometimes i get a good spirit that calms you and tells you not to be afraid then other times you get the dark entity.It's been 10 years since i started have this happen to me and my best solution is preventing it from happening.I also noticed that this usually happens to me when i fall asleep while i'm hot.So I started going to sleep with the a.c on blast and this works very well but winter time i have to jeep a fan by my bed at all times blowing in my face this helps to but sometimes i get under the covers and thats when it happens but i know when its happening and I have three ways to control it if it occurs 1.Pray to God or Jesus and repeat there names until the entity leaves.2.Try to focus on a part of your body and try move it like your hand your head,legs or your foot usually once one part of your body moves you wake up from it.3.Give in just stay calm and try not to panic pray while its goin on close your eyes you usually fall back asleep before waking up to it again but sometimes you just wake up.but i would just try if your in a hot area to just turn the a.c on before you go to sleep or if in a cool area keep a fan around you when your goin to sleep I live in Ma so i use both.Good Luck On conquering this entity

Similarities

In writing this I've found similarities in our SP. And this happened to me for the first time last night. The voice I heard was from a past lover, but she was speaking evil. And in reading your account I noticed the scenario where you were on a single mattress located on the floor with the closet opened. Well. my bedroom setup is a single mattress on the floor, with my closet always opened. And the figure was female and completely dark. She was to my left squatting while holding my head close to hers so she could whisper in my ear. These cases all have their coincidences, but they are unexplainable.

Ok so I had one of these episodes about 3 mornings ago, though mine started the same as everyone elses, i.e, I wake up and can't move, but with me the next thing that happened was loud buzzing and then it was like I had an epileptic fit, my body was shaking and I could feel my eyes rolling in my eyelids, I was completely conscious and knew what was happening so I don't think I have epilepsy.
I spoke to my mum who goes to a psychic circle once a week that is run by a medium, and the medium told me that this is not caused by spirit, it is simply that your conscience can leave your body while your asleep and sometimes you wake up and your conscience isn't back in your body yet and the fittting is my conscience re-entering my body so I can fully get up. It only lasted about 20 seconds and then I was fine and could get up. It had me pretty scared as I thought it was some evil spirit coming to get me, but from the sounds of things it is something that I will just have to learn to live with :)

Sleep Paralysis

I used to have these incidents once in a while were I fealt like I was going to die in my sleap while awake. I couldn't control my heartrate my mind was making me hear loud noises and dream and I couldn't move. I kept telling my hand to move in a panic desperate to wake completely. It was only once n a while but last night it seemed to last the entire night. I called my doctor and he said it was because I stopped taking Paxil too fast. I thought there was a band outside my window, and my bedroom was the livingroom. Then when I finally did wake up I realized it was silent, but I couldn't stay awake so it kept happening. Im afraid to sleap tonight, but I will say my prayers.

Sleep Paralysis

This is one of the major symptoms of narcolepsy. It's not a bad idea to go get tested at a sleep center. I just went to Jefferson Sleep Disorder Center in Philadelphia last april and was dx with Narcolepsy. I have all symptoms. After 10 years of shrinks and discussions I finally went to sleep center and now the meds keep it at bay and it's wonderful.

For those who are tormented and scared

Try an experiment get a bible and somehow open it and attach it to you
while you sleep like a Teddy bear cuddle it open over your heart. I can guarantee if it's open
on you, you will NOT have an SP. Prayer helps too. The demons are out tormenting
because there time is almost up.

Oh please

This is scientific, you can gaurantee no such thing.

I never experienced this

I never experienced this before until last month. I heard of it but never experienced it. I always sleep on the right side of the bed and my boyfriend on the left. I was sleeping straight on my back and fell into this state where something on left was coming close. It felt so evil that it made me go crazy. I was trying to wake my bf up by yelling and even biting him so hard but he never woke up. I was watching myself crazy in the inside but then I felt paralyzed then see myself unable to move, very stiff. I finally woke up and heard these voices, it took me a very longtime to feel like myself again. I couldn't sleep for hours after that, scared out of my mind. The next morning I asked my bf if I actually bit him, we checked his arm, there was nothing, weird cause I really felt the sensation of biting it was so real. NOw it seems like I have this OCD of wanting to sleep on the left side of the bed now, I was even arguing with my boyfriend to have the left side. One night, I felt so unsafe that I went to go sleep with my mom, I mean I'm over 20 years old and felt so vulnerable. Also, I'm really scared to sleep now, I feel like something is around me once I close my eyes. I hate this feeling.

I know what you mean

I am over thirty and if my mom lived with me after I had one of those SP episodes I would tell her to move over because I am getting in. I might even snuggle close just to feel safe. These dream states will make the bravest soldier want to crawl in bed with his mom too.

Demons

Hi I lived in a house where two people killed themselves in the 60's
and in that house I experienced all of those sleep paralysis and visions etc..
The house was demonic for sure. If you are truly suffering pray before bed Psalm 91
and the lords prayer. Call out in the name of Jesus Christ leave. Keep a bible opened up on you or under your pillow. It won't happen! I suffered in that house but the bible was the ONLY thing
to make it stop. Trust me on this it works. Look up deliverance on google and you will find some

I just had one of these

i just had one of these experiences about 10 mins ago.. i was sleeping on my side facing the wall of my room and all of sudden i felt something massaging my back. it was someone..and then i heard their voice whisper something to me and i figured it was a guy i had encountered a couple weeks ago in the streets trying to offer SEX to me.. creepy old man in his 60s id say..i saw his shadow over me and tried waking up and screaming and he wouldnt let go..and i couldnt move at all. and i kept screaming and screaming till i woke up.. -_- pretty scary feeling :C i woke up breathing heavily 0_o second time this happens in 3 months :O hm.

SP and Exploding Head Syndrome?

Any research on the relationship between SP and Exploding Head Syndrome? I suffer from both. Interesting, too, in that I seem to be the only one, based on reading the posts, whose SP episodes do not include any sort of paranormal hallucinations. I'm merely paralyzed until I can break myself out of it, nothing else.

SP and EHS

I'm 42 and get both. Now, the EHS is more common, though, since I don't sleep on my back anymore. My SP would usually consist of nightmares where "something was approaching" (evil) but I never ended up seeing it. Sometimes, it would just be me seeing the room and feeling the same thing.

Since I don't sleep on my back anymore, what I get nowadays are freaky nightmares where I wake up, still dreaming, and see some shade, shadow or half outlined "thing" - blob, whatever - in my room. Many times I yell out loud, yes, and wake myself up, yelling. It's embarrassing. Hope this helps.

It's amazing how much

It's amazing how much information there is now.

I first started getting sleep paralysis in 2003. It was so frequent that I would get it three times a night. I ended up becoming so used to it, that when I woke up and was paralysed, I'd just go back to sleep and wait until I woke up next time and wasn't paralysed.

I was 17, and went to a neuropsychologist who didn't know anything about it either. but looked it up and told me it was the body not telling my brain it was awake.. duh.

I haven't had it for 7 years and have just started having them again. All I can do is breathe really rapidly until my partner moves me and wakes me up. If I fall straight back to sleep, I go straight back into it again. this happened about 6 or 7 times last night. I need to make sure I get up, go to the toilet or something or walk around. then go back to bed and it won't happen again that way..

So glad to see that 7 years later, there is so much more information about it!

In my opinion, every time I have had sleep paralysis, it has been in the 2 - 3 weeks after any recreational amphetamine use I have used.
One of my friends also experiences it 2 - 3 weeks after using any amphetamine recreational drug.. has this link also proven at all?!

I Just had one 5 minutes ago.

i Just had one 5 minutes ago. The scariest on i has was when i was 19 when i couldnt move and i saw someone looking down at me i was scared shitless

Sleep Paralysis

I went to sleep last night at around 1.30a.m n was woken up by 3.a.m bcoz of some heaviness i felt in my left fore arm. i woke up with a start as i realized my left arm felt like it was dead. completely numb.. like there was no blood circulation.. completely numb n after pressing it for a min with the other arm i felt a sudden rush of blood through it. i got up from the bed completely freaked out.. head to the washroom n then suddenly my room's door opened a bit. i am anyways afraid of the dark then the numbing of the hand n then the opening of the door without me touching it was enough to make me feel the presence of someone else in the room. after going back to bed i kept the lights on.. i could hear sounds in my room i could see the curtains fly (which is strange as all the windows were shut to let any wind in) then my carpet which was rolled up and supported at the other window slid sideways drawing the curtain open n suddenly fell to the floor with a thud. it may seem like a scene straight out of the movie but it all happened. n for a moment there i felt like it was someone there holding the curtains n not just the carpet. suddenly my phone light went on for a second n off again. this cannot be sleep paralysis.. i cannot be imagining things to this extent.
Is there any logical explanation to this.

I cannot say that there is

I cannot say that there is any good physical explanation to what you are experiencing but from a logical standpoint I can safely say that you are not having a sleep disorder. It cannot be explained by science in this case. From what I've read in multiple stories about SP experiences I've been able to come to the conclusion that something spiritual is involved. You may not believe in demons but I do think that you are experiencing one at the moment. The demon is trying to torment you and ultimately overtake you and I know that the best way to overcome is to pray about it. Pray to Yahweh and look to the Bible for insight on the connection between God and man through prayer. Demons are fallen angels and are scary but they themselves are terrified of God. Let God come near to you and these demons will be overcome. I encourage that you look into the Bible once again on prayer. If you have any questions at all my e-mail is Feel free to send me a message if you ever get the chance.

Checking

hello, i was on the serendip website i saw ur post to another user about demons. u said ur email was free to send messages to, i dont know how this site works if this goes to ur email or what. Hope u understand my hesitance to talk without knowing if this is in fact u.

First time to check on this

my names luke.this has happened to me bout six times since i turned 18.i wake up and cant move or talk,its so scary when i do come out of it i cry.ive only told two people.i just decided to look on internet to see wat it is.im glad im not alone.i never had heard or seen things,my body felt like it was getn a light electricity though.but fear so bad im tearing up now thinkn bout it.i live in louisiana.someone tell me wat it is please.im 21.

It not just normal SP but more than that!

hi i just amazed by the number of people experiencing the same thing as i do. It happened several time now. The last time is about two days ago. while i was taking a nap. And suddenly it happen. But mine is quite different. Before that thing happen i already awake and i still can move my body but suddenly after a while a buzzing sound started to appear and after that i became completely paralyzed. But the weird thng is, I am fully awake at all time. My eyes are totally open and i fully aware of the situation. I just said " there we go again" The same thing happen to me again. So after that i start praying to God to deliver me. I tried so say a prayer but my mouth completely shut. It took me several minutes before i can really say a word. But as it say it, the SP just gone just like that. I dont have any breathing difficulty nor seeing something weird and scary now. But thig are different before. It started to happen when i move into a new room in my campus just a few month ago. On the first day i move it started to happen. The first and the second time is the most severe but after that i just relax when it happen. In my first experience, i did saw somthing bizarre. I saw a dark figure standing by the door and suddenly like surround me after that i started to became paralyzed. Then i prayed after that it gone. But you what i told my friend that morning and the next day he also experience the very same THING! Weird! He told me and i couldnt believe either but one question remain if it really just sleep disorder does it contagious too? the i also did heard a voice but lately when i experience it i just relax and pretend nothing happen. Now i want to ask, why does it only happen after i moved to a new room? why does after i told my friend about it, he also experience the same thing? Then why after i prayed it stop happening? Why i am totally aware of surrounding when it happen? (I can even look at the clock on the wall as it happen). One conclusion i can make from all this. This is something more that SP could explain. I think it must be 'somthing else' which beyond our logic could comprehend.

Hey I think that you're issue

hey I think that you're issue is something much more than a simple sleep disorder. I have read over many differing stories of other peoples experiences and have come to conclusions that spiritual forces are involved. Prayer is affective in these situations because God will act against demonic presences which you are probably experiencing. I encourage you to look into reading the Bible on the subject of prayer and its connection to God. Prayer gives anyone who is willing to know God, a direct line of communication with God. Demons are scary and they can do scary things but they themselves are terrified of God and likewise run when a person calls on God's name. You don't have to take my advice but I recommend looking to God through the Bible and prayer. My e-mail is if you have any questions. Feel free to ask any question at all or we could simply talk about it.

It gets freaky when someone

It gets freaky when someone calls your name waking you up and you find yourself unable to move or talk no matter how hard you try. Its most terrifying when the person calling your name is someone you know and can recognize. My guess is your subconscience and conscience minds are working together at the same time. You are awake and fully aware but still asleep and able to dream.

Story of my friend

After having several cases of sp i remember my friend telling me about his outrageous stories and i never believed him. He would tell me about this dark figure hovering over him. He told me it all started when he opened his door after hearing it trying to open. Ever since that, he has these moments when he is asleep and then he is awake but can't move his body and he just watches as his family members watch him sleep, hoping that they will touch him so he can move again. After hearing this, i just believed it was sp, but he told me that one incident after having the feeling of being pushed down he was sometimes on the floor and one time he had ropeburn like marks on his wrists and ankles. It was really freaky and i started to doubt that it was merely sp and that it dealt with a spirit of some sort.

Hi all, i didnt think this

hi all, i didnt think this would happen to so many ppl..to all who do not believe in evil spirits..this is exactly what it is..these spirts will try to still your souls if you dont fight it..ever heard of cases where ppl die in their sleep? matrix? exactly. best advice is to move your toes and feet..fingers..these limb are hard for the demons to control. keep moving ur feet and u will wake up. there are ways to scare these spirits away ..you need to seek a shaman. i heard there are fruits of some sort that you place near your bed that will help..best of luck to you all..stay strong!

WHY IS IT HERE?

I go to sleep and wake and i cant move i've experience this at least 20 times i've counted and i never feel my nose breathing and i never seen anything yet but i still cant move and hear things around me its scary but i have to live with it

OMG. I totally freaked on one night!!

last week I was sleeping when I awoke suddenly and I felt like I was being watched I opened my eyes and there floating above me was an iridescent. something like a creepy old man smiling in a hooded outfit.LOL!! he looked like igor from young frankenstein now that I think of it. anyhoo. I closed my eyes and can you believe the imprint of his image as in my eyeballs as if he was lite and so I opened my eyes really fast and I thought. WWWWTTTTFFFF. and he turned his head sideways as if to say what you don't believe me? I grabbed the blanket covered my eyes and called out to my boyfriend who promptly woke up,looked up and grabbed me. he said do you see that? he saw it too. unreal!! Also I have 3 Chihuahuas that will sit and stare at a corner of the bedroom for hours with their heads going sideways one way then another as if they hear a most intriguing noise. aannddd my cellphone would literally fly off the dresser top and out the bedroom door into the hall in front of me. it finally broke. Now that I know what we were all experiancing. LOL!! what a relief cause I thought I was losing my mind.

Dont buy lies, when you have the TRUETH

When do you buy all these lies about what whens to you when you are a sleep? number one facts if you doubt your self concering what you was, your boyfiend was it too, on this website others have tell of what they have seen, could so many people be going mad in the same direction of see things or hearing things while half asleep? some even not asleep, i can tell you this cause i have been have these for 20years so i know what i am saying, thse hapenings have nothing to do with sleep paralysis, what is happen has to do with DEMONS but not many people are will to tell the truth, i can say this cause i went in deep to get answers, At age 10 or 11 was i started to fell them touching me on my legs like a massage when i told my mother that someone or some thing keep touching me see didnt understand or may be dont beleive me then(she does now, listen DEMONS are real and they are not nice or a good spirt they come only but to torment you. JESUS alone can help you, he has for me, now when they try me i call upon JESUS, because they will come cause they are nothing but evil and evil is evil they cant be nothing esle, please take the time out to kow the trueth and dont just buy any answers when you know what your eyse was, if someone had told you you wouldnt have beleive but you was it for your self so why buy lies for an answer?

I agree as well. Anything

I agree as well. Anything that people don't understand, they have to put some type of label on it and what better than to say that it's all scientific! Pish Tosh! Spirits are very real and I truly believe that at some point and time, we've all experienced them, even these "scientists". Any age, race, gender, as well as animals are not exempt when it comes to contact. I've been experiencing this sleep phenomenon eversince my mother passed when I was 14. Now I'm 34 and they're coming more frequently. However, at one point it had gotten so bad to where I'd be afraid to even lay down for just a nap. But then I learned to deal with it. Instead of trying to fight against it, I now go with it and maintain calm breathing. So I started going to sleep either on my stomach or side because on my back is where I felt the suffocation and the most afraid. Like you, I've experienced the left over impressions of them tickling my sides. When I awaken, I still feel where I was touched. I know I'm not going crazy and I'm glad I'm not alone with this. Although there have been some instances where people have seen their spirits, they won't allow me to. Meaning there have been a few times when I would be asleep on my side and I've felt the presence lingering behind me. When I went to try and turn over to see, it kept pushing me forward so I couldn't see it and I thought that was the weirdest thing. Also, now that I have children, it has been passed on to my oldest daughter who's now 9. She had her first experience at the age of 2. She didn't have the sleep thing, but she saw the demon in the corner of the room by the closet. I woke up to a serious loud cry like she'd been scared out of her mind. I tried to lay her back down where she was before, she almost knocked me over trying to get away from that area. She still sees things and I try to help her through it as best I can. Lastly, this whole experience goes even deeper than just sleep for me. I've seen the faces of demons on people and boy that is not something I wish for anyone to beable to see. It's the scariest thing ever. I've seen shadows throughout the house, heard knocking on the door, lights flickering, had a demon voice to tell me to "Get Out!" at the old house I was living in while in Georgia and my male friend heard it too. I've had spirits to go through my body into the back of the couch. It's crazy, but it's my reality and can't no scientist explain it with a scientific melanonin theory.

Demons

Hello anetta, I am a lot more
Aware of what I have gone through
Because the other night something
Lifted my legs when I was asleep
And tonight I slept with my window
Open when it was very foggy outside
And in my lakota culture sleeping
With a window open is bad, anyway
I was fully asleep when I dreamed
Of a man who came from the devil
And he was standing outside my
House window waiting for me and
When I tried to wake myself he
Wasn't letting me so I tried rolling
My body around I couldn't move,
So now I'm awake here at home and
I'm scared to go back to sleep.
I burned some sage and prayed for
Protection and asked him to leave
Away from here. Its quite disturbing. I
Just found myself as one of gods
Soldiers and maybe this is why
Deamons are trying to scare me.

A Form of Sleep Paralysis

I'm pretty sure I have a form of Sleep Paralysis. It has been happening in the past few years. It never used to occur as much as it does now, it occured only occasionally. But lately throughout the past few months it's been happening almost everytime I take a nap, but never during a nights sleep. I feel like my mind is awake but my body is asleep including my eyes. When this state of sleep comes, all I can do is make a faint wimpering sound in the hopes of my roommate hearing me and trying to wake me up. To wake myself up I have to jult myself but I feel paralyzed trying to do so. I have never experienced or seen any evil spirits or felt anything holding my body down. Can someone help me figure this out?

Same problem

I have exactly the same problem you have. Its been going on for years, I think it started when I was about 13.Fortunately for me mine do not come with any wierd noises or "visions",but I had an aunt who was always complaining of demonic attacks where she could see the demons enter the room and sit on her chest.This always led her to accuse a lot of people around her of being witches. Though I believe in demons I am more inclined to go with the scientific explanation for the episodes,which also happens to coincide with the explanation my mum gave me years ago: your mind is awake but your body is still asleep. When I started experiencing it,i would always try to call God's name Jehovah until I could move again,but as time passed I realised that even without any spiritual help it always passed in less than half a minute, convincing me that it has nothing to do with demonic attacks. Like you too it only happens to me when I nap in the afternoon, in fact an episode yesterday afternoon made me google it. I've decided to just learn to control my panic and go back to sleep if possible though that is easier said than done.

Sleep paralysis

i have experienced the same, my body asleep but mind awake. its pretty scary. when i do finally wake up with body able to move as well im scared out my mind and i even cry sometimes cause i never new what was wrong. but i also dont experience no evil spirits see ghost or anything like that. i try everything i got to move, kick or scream but nothing ever happens. i feel like im screaming but must not be cause my boyfriend hasnt said anything about it yet. it use to happen to me every night but then it went away for a while and now its doing it again. im glad i looked it up so now i can understand a little about it and that im not the only one experienceing it. thanks

I've been meaning to do research on this for a while, but I always forget about it the next day. Last night however, I had the most intense sleep paralysis I've ever had, which caused me to Google it this morning. I happened to be watching The Exorcist, which I think may have contributed to the evil hallucinations I experienced. I turned it off when I was tired but as I was falling into my sleep state, I would hear a buzz, which would wake me up again, and this happened a few times. I also heard other noises, like people shuffling and moving around in my flat. I've never experienced SP more than once in a night, but last night it happened every time I fell asleep. I saw and heard a number of different things, from people breaking into my flat, to a darkly dressed Asian guy standing over me and watching me while I lay there, unable to move. When I snapped out of it, I was looking at my towel hanging on the cupboard door. When I sleep on my back I can guarantee that it'll happen, so I avoid that at all costs. But last night I was extremely tired, which I've read can also cause it. It also happened to me at work, I felt like my boss was watching me sleep but when I pulled myself out of it I was alone in my studio. But it made me think, what if he had come in and I was paralyzed.. He would probably think I was a complete mental case. Anyway I'm just glad I'm not alone on this, nice to read everyone's experiences. Next time it happens I plan on embracing it and seeing if I can be a bit more relaxed and in control of the experience. Thanks to all..

Not Asleep

I'm just an ordinary scottish woman & I honestly thought I was crazy when this happens to me when I sleep. It's been happening to me since I was a child.
I just found this by accident on the net & I don't think calling it just
"Sleep Paralysis" because Iam NOT asleep when this happens to me. my brain is fully awake and I know it is Satanic of some sorts I know I feel a buzzing taking over my entire body then I feel scared as if somebody is trying to take me away.
I also feel as if something is attacking me and I hear. like laughing it is by far the most "Real" thing & NOT sleeping.
Can anyone help me to understand what exactly is happening to me.

This sounds exactly what

This sounds exactly what happens to me, I've never seen anything like other people seem to experience

But that buzzing taking over my body is the perfect way to describe it and I feel like someone is trying to take me. I try to stop it by trying to move my hand or scream, it rarely works.

Actually just been woken by this now, happened 3 times with in the space of an hour and now I feel to scared to try go back to sleep.

I know this has been happening to me since I little, I'm 25 now. I just wish I could stop it or at least understand it.

What worries me more is that I'm pretty sure my 2 year old daughter has started to experience it.

If anyone could offer any advice or explain more about this to me, I'd be very grateful.

WTF is going on with me?

Is there any way to explain why I am almost fully aware in my dreams to the point I can wake myself if it gets to intense? I also wake up almost every night still dreaming for up to 30 seconds and then like everyone else I have a really creepy feeling like a ghost or evil spirit is near even if it wasn't a dream about that because usually it's I wake up and I'm in bed but I still feel like I'm on a crashing plane (it's very intense to the point I hear others and see the ground coming closer and closer from out the window and I feel major turbulence yet I'm almost subconsciously aware that I'm in my bed) and I'm able to pull myself out quite quickly before impact. Another dream I have on a regular basis is running from a tall black man (the same one every dream whom I've never seen) and he is trying to shoot me and I always come to a dead end and know he is about to find me and he always does and he shoots me in my head and I actually can feel the pressure of the impact. I don't know what will stop these I'm going to try and monitor what time I wake up from the what I call "terrors" and I'm going to have someone wake me up before that time to see if it will interrupt the terrors.

I have experienced sp several

I have experienced sp several times even up to five times a night and it is really creepy. It only happens occasionally, i pray everytime it happens and i start moving again, but then it happens almost 5 minutes later. The weird thing is, is that when I turn my lights on and leave them on after being frightened, the sp stops.

This has happened at least two times to me, maybe more but I've probably discounted them as being regular dreams the ones I won't forget or can't discard are the scary ones, the ones that you know you're awake, that feel like something is holding you down with unexplainable (until now. maybe) sounds, mine have been growling right in my ear, hell I can almost picture the doberman it's that vivid, but I've never seen anything. I will try to move, try to scream but nothing works at best I think I can muscle a pathetic whimper with what feels like the fight of my life but I don't know if its audible on the outside, I do believe in God so I also believe in the devil and demons so I'll concentrate really hard on Gods name, Jehovah, and try to speak it. it always takes a couple times of trying but I can usually start regaining movement and voice slowly .If this is strictly a body malfunction thing maybe repeating Gods name has a relaxing effect which helps me out of it and if it is something more spiritual I know Gods name has authority there.

Well spoken

you have spoken well about God and him helping you what you are experenceing is most certaingly demons, they are so real just that most people hate the trueth but if you get closer to God he will give you deeper insight on what is going on, he has for me, put your heart in him your whole heart and see the resolt. GOD BE WITH YOU!

Now i know im not crazy

I wake up can't move or talk and I always see this black hand in front of me. At frist I pay it no mind but then it keeps happening. Then one nite my girl seeps over and I get up and get ready to go to school like every morning and I tell her I'm going see u when I get back and turn off the light and the same thing happens to her but it never happend till she slept over so give me a answer. To that one because I would love to know

This issue of a black hand is

This issue of a black hand is not simply a dream or sleep paralysis of some sort. I think that you are facing demonic activity in which case the presence of the demon is in your house. Your girlfriend experienced it when she stayed in the same place. I encourage you to look to God through prayer and seek out information on the power of prayer in the Bible. Demons are scared of God and they will flee his presence so I encourage that you guys look into speaking with God on the subject. I encourage research into the Bible on God's power and his existence. You don't have to take my advice of course but I definitely know that looking to God would be worth it. If you have any questions at all my e-mail is Feel free to ask or comment on anything that you like and I'll try my best to answer any questions you may have.

Sleep Paralysis.

For the past few years I've had 1-2 a month of being unable to breathe whilst sleeping on my back, it only ever happens if I'm Extremely Tired or I have an ailment where my nose is blocked and I have to breathe through mu mouth. I am asleep and unable to wake up, though whilst sleeping I am also aware of my breathing difficulties and I make noises in my sleep to attract the attention of my wife who duely wakes me up and out of my sleep paralysis. My heart beats like 100 beats to the minute when I do finally get woken up and I can remember everything about my experience. Recently my wife was out in the afternoon and I felt tired and unwell and again experienced this event, there was someone in the house who heard me making noises but they did not know why and did not want to intrude on my privacy, it seemed to last for 10-15 minutes and I knew I was choking in my sleep and just as I was about to give in to this encounter and accept I cannot wake up I managed to wake myself up, this is only the second time I've managed to do this, as on all other occasions either my wife wakes me up or I wake someone else up in the house with the noise I am making whilst experiencing this event. Maybe it's my throat muscles closing and restricting the oxygen, I don't know, all I know is it's not a nice experience and I very rarely sleep on my back, unless I cannot get to sleep. Thanks for listening to my experience. David.

CPAP Machine and Sleep paralysis

I had Sleep paralysis at a very young age and still have them occasionally. I believe the symptoms occur when stress and lack of sleep prevents you from getting a good nights rest. Five years ago, I was diagnose of having severe sleep apnea and just started to use the CPAP machine again after not using it for four years. I felt better for a few weeks and started to exercise by walking 2 miles every day to lose weight. Just recently, I had an episode while using the CPAP machine that I went into a deep sleep paralysis and cannot move and breathing became very difficult. I started to panic that I'm going to die in my sleep but cannot snap out of it until my partner heard me mowning. Even with the CPAP machine on it didn't help me. I was terrified and was wondering if anyone has gone through what I just did.

I have not experienced your

I have not experienced your particular situation with the machine, but I'm well aware of the frightening sleep experience. Too, I hate to say this, but see, even machines can't help what is happening to us. This isn't something that can be scientifically corrected. So what if they come up with all of these big words and all types of brain chemicals that release and shut off at certain times, we'll still experience it no matter what. I mean you've just proven that. I wish there was a better explaination, but there isn't and because there isn't, scientists feel that they have to put it in some type of category with brain and muscle malfunctions. Who wants to hear about that? Well, I do hope that you are able to find your answer and if not, you may have to just do like I had to learn to do and that's to accept it as part of your reality. I don't know if you believe in God, Jehovah, Allah, etc. but he's also a great cure for whenever those times arise. I wish you well and good rest.


What Octopus Dreams Tell Us About the Evolution of Sleep

To revist this article, visit My Profile, then View saved stories.

Fruit flies, octopuses, birds, and humans don’t seem to have much in common. Some live on land, others are aquatic. Some fly, while others are earthbound. Some are vertebrates, others lack backbones. These creatures evolved separately and their common ancestors are far, far back in the evolutionary chain. But they may share one fundamental feature: They dream.

Nearly all creatures sleep, though there’s some debate as to whether single-celled organisms like paramecium do. But no one really knows why. For years, researchers have bandied about theories that sleep helps with memory, growth, and learning—and it’s clear that humans need sleep to function properly—but there’s little else that’s well understood. “Sleep is this big black box,” says Marcos Frank, a neuroscientist at Washington State University. Frank likens sleep to a mysterious organ: It’s clear that it exists and is vital to animals’ health, but it’s exact function and the mechanisms that control it are still unknown.

It’s even more mystifying that some species appear to have only one sleep state, during which their brains are relatively quiet, while others seem to experience two kinds, a quiet phase and an active state. In humans, the period when the brain lights up with activity is called Rapid Eye Movement (REM) sleep. It’s when we dream and when we are the most difficult to wake up.

For a long time, scientists hadn’t observed this deeper, active sleep phase in amphibians or reptiles. So until recently, the theory was that it evolved later in history, via an ancestor shared by birds and animals. But in 2016 active sleep was recorded in lizards. Then in 2019, the state was described in cuttlefish, and this March, a team of scientists in Brazil published a paper in iScience identifying it in octopuses. Cephalopods like these evolved eons before the rise of creatures that would have shared a lineage with both birds and humans. “There’s no way there’s a common ancestor there,” says Frank. Now scientists are wondering if this sleep state is more common than they initially realized, or if it developed in different species at different times, the way wings and flight arose separately in insects, bats, and birds, a phenomenon called convergent evolution.

Understanding which selective pressures caused this adaptation and the preservation of the genes that code for it could help scientists understand what function dreaming serves for the central nervous system and why sleep is important at all. “What is sleep doing for animals?” asks Sidarta Ribeiro, a coauthor on the paper and the director of the Brain Institute at the Federal University of Rio Grande do Norte.

The first step in studying how animals sleep is to figure out when they are, in fact, asleep. This is more complicated than it sounds. “Imagine you were on Mars and you found an organism,” says Frank. “How would you know if it were asleep or not?”

For mammals, scientists might implant electrodes in their brains to track how their neurons are firing. But octopuses have a highly distributed central nervous system. Instead of concentrating control of their nervous system in one brain, they have eight ganglia in their arms that often act independently.

Rather than using an invasive method like attaching probes to determine the octopuses’ sleep states, scientists at Ribeiro’s institute studied a few of their behavioral characteristics. Sylvia Medeiros, a graduate student and the lead author on the study, tested the animals’ arousal thresholds. Three of the lab’s four octopuses were given a visual stimulus—a video of moving crabs. One got a vibratory stimulus, in a form of a light tapping on its tank. Medeiros wanted to see how quickly they responded to stimuli when they were awake. Then she tested them when they seemed inactive, and measured their response rates. Slower reactions meant they were more deeply asleep.

The team also trained cameras on the slumbering animals to observe changes in the patterns on their skin, which offer clues about their brain activity. When they’re awake, octopuses change color during courtship, when they’re fighting over territory, and when they’re hiding from predators. Those changes are always in response to what’s going on around them. But, says Medeiros, “What we observed with sleep is that this changing color is not related to what is happening in the same moment in the environment.” Instead, the octopuses were changing into fantastical patterns that had nothing to do with real world stimuli, like the proximity of other creatures or a need to camouflage themselves. Because motor neurons in the brain control those skin pattern changes, Medeiros says it’s possible that these patterns were emerging because the octopuses were dreaming.

For example, the team’s paper describes a brief state called “quiet half and half,” when the octopuses exhibited a striking pattern in which one half of the animal is completely white, and the other completely black. This pattern normally appears during courtship or turf fights. Since it was obvious that the sleeping animals weren’t engaging in those activities, the researchers wondered if they were dreaming about these scenarios and broadcasting the dreams on their skin. But the team has a caveat: The octopuses also aren’t in their deepest sleep at this point, so it’s possible this could represent a gradient of drowsiness as the animals fall asleep.

Even though the team’s study only included four octopuses, which might seem like a small sample size, this is normal for this kind of study, says Teresa Iglesias, an animal behavior scientist at the Okinawa Institute for Science and Technology who was the lead author on the 2019 cuttlefish study. She says that the results are robust because the behaviors were so strong and consistent: Three of the octopuses had similarly delayed reaction times depending on how awake they were. (One octopus was excluded from the arousal test results for technical reasons.) All four changed skin color during active sleep.

Igelsias says that there is “stronger and stronger evidence” to suggest that cephalopods do indeed dream. When she did her cuttlefish experiment two years ago, Iglesias struggled to figure out when the animals were fully asleep. Their arousal thresholds weren’t consistent. After weeks of recording them, she decided to sit down with the videotape to figure out other indicators that might give her a clue. That’s when she noticed that their skin patterns changed. Just like the octopuses, those patterns didn’t match up with anything happening in the animals’ external surroundings. “What we’re seeing is neural activity on the skin,” she says.


What to Expect in Your 50s

by Beth Howard, AARP The Magazine, October 2012 | Comments: 0

Fifty-one percent of Americans think they actually look younger than their age.

Staying mentally and physically active can help keep you, well, younger — particularly in your 50s, when you may notice the first subtle changes in your metabolism or skin.

What can you expect this decade? Everyone ages differently, and lifestyle plays a major role, but you'll experience both hard-to-notice and impossible-to-miss changes in your physical and mental health.

Read on for the good, the bad and the what's-up-with-that? transformations you'll soon encounter — plus the latest advice on feeling happy, sexy and pain-free.

Save Your Skin

The Good News: The likelihood of getting an outbreak of acne on the day of your son's wedding is greatly reduced. That's because your skin is getting drier, making blemishes less common.

The Not-So-Good News: The loss of muscle, bone and fat under the skin — along with changes in collagen and elastin — is making fine lines and wrinkles more dramatic, especially if you've smoked or sunned significantly. One remedy: prescription retinol products like Retin-A or Renova, says Helen M. Torok, M.D., medical director for the Dermatology & Surgery Center at Trillium Creek in Medina, Ohio. These creams repair damaged skin by speeding cell turnover. Pick skin products with antioxidants and glycolic acid, which promote skin thickening and increase collagen production.

What's Up With That? In your 50s you're likely to notice age spots and skin tags. For the former, consider trying a dermatologist-prescribed hydroquinone product — "the gold standard for reducing age spots," Torok says. Skin tags are usually benign, if unsightly. A dermatologist can remove them through freezing, snipping or cauterizing.

What's Ahead: In your 60s you may develop dilated superficial blood vessels (called telangiectasias) on the cheeks, nose, chin and legs, but don't worry: Doctors can zap them with a laser that destroys the blood vessels underneath the skin — with no scarring. Other options to help make skin look younger: radio-frequency-emitting devices that tighten the skin, and plasma skin resurfacing. Also, Botox and injectable fillers like Radiesse, Restylane and Juvéderm can reduce wrinkles.

More than 150 million Americans wear glasses or contact lenses.

Preserve Your Senses

The Good News: Your senses of taste, smell and touch remain mostly intact.

The Not-So-Good News: You'll probably need reading glasses. The cause? As you age, the lenses in your eyes stiffen, making it harder to focus up close. You may become sensitive to glare, and your night vision may decrease, as those same lenses begin to lose clarity. Plus, dry eye becomes more common, says William B. Trattler, M.D., an ophthalmologist at the Center for Excellence in Eye Care in Miami, Florida. Medications like Restasis can help, as can omega-3 fatty acids, found in fish like salmon.

What's Up With That? Floaters, tiny specks of debris in the eye that cast shadows on your retina, can appear in your line of vision. They are typically harmless unless you suddenly see dozens of them.

What's Ahead: Hearing loss becomes more common in your 60s, due to the effects of a noisy environment.

Motivate Your Metabolism

The Good News: While metabolism typically slows up to 5 percent per decade, that doesn't mean you have to gain weight. Just stay active and gradually decrease calories, eating more nutrient-dense foods, including whole grains, fruits and vegetables, low-fat dairy products and fish, says Alice Lichtenstein, D.Sc., director of the Cardiovascular Nutrition Laboratory at the USDA Human Nutrition Research Center on Aging. "We have fewer 'free' calories for sweets and soda."

The Not-So-Good News: Your stomach empties more slowly, which can increase the risk of reflux. And the slowing of digested material through the large intestine can trigger constipation, says John I. Hughes, M.D., a gastroenterologist with the Kelsey-Seybold Clinic in Houston. The easy fix? Fiber and water. Adding fiber to your diet may also help protect against colon polyps. One in four people in their 50s has colon polyps that may develop into cancer, so you should get a colonoscopy.

What's Up With That? After years of guzzling milk shakes with no problem, you may find yourself suffering a dairy hangover — specifically, stomach bloating and discomfort. That's because many people in their 50s produce less lactase, an enzyme that helps digest milk. Even if you're lactose intolerant, you may be able to eat yogurt, which contains active bacterial cultures (known as probiotics) that can help digest lactose.

What's Ahead: In your 60s and 70s you may secrete less hydrochloric acid, which decreases availability of vitamin B12, says Lichtenstein. Ask your physician whether you should eat more vitamin B12-rich foods or need a supplement.

41 percent of Americans say they’re “optimistic” about getting older.

Bone Up for Good Health

The Good News: If you've been active all your life, your bones, joints and muscles have a better chance of being in pretty good shape during your 50s.

The Not-So-Good News: Aging and inactivity can lead to achy joints because of the wearing down of cartilage, the loss of lubricating joint fluid and weaker muscles. Some remedies: maintaining a normal weight and strength training.

What's Up With That? Your joints may sound like snapping twigs, but those creaking and popping noises are usually not a serious problem. They may be ligaments tightening around a moving joint, a tendon snapping over a joint, or nitrogen bubbles "popping" in the fluid inside a joint. But talk to your doctor if these sounds are accompanied by pain, swelling or numbness.

What's Ahead: An estimated one in five women 65 to 74 has osteoporosis. Strength training can help.

Keep Your Heart Strong

The Good News: If you're healthy and active, you will likely get a lot more miles out of your ticker. It's never too late to do your part: Grab your swimsuit, bike or running shoes and get moving.

The Not-So-Good News: Your heart's walls are getting thicker and its valves are stiffer. Also, many people in their 50s will start to develop the first signs of heart disease. Thanks to new treatments and the mitigation of risk factors like high cholesterol, though, the death rate from heart disease declined 27.8 percent from 1997 to 2007.

What's Up With That? Have you noticed a skipped beat or a racing heart? It could be atrial fibrillation, a type of heart arrhythmia that becomes more common with age. Since it can increase the risk of stroke, mention it to your doctor. You should also tell him or her if you're experiencing unusual fatigue, weakness or dizziness when exercising.

What's Ahead: Heart disease is the leading cause of death for people 65 or older. Experts suggest that exercise cuts the risk.

74 percent of men and 70 percent of women say their sex lives are better now than at 40.

Improve Your Sex Life

The Good News: Sex after 50 can be better than it was during the child-raising years: You've got more time and fewer distractions, and you're not exhausted from day-to-day child-care issues.

The Not-So-Good News: Sex-related hormones — estrogen and progesterone in women, testosterone in men — are declining in your 50s, although these decreases are less likely to diminish your sex life than are bad habits like smoking and a sedentary lifestyle.

What's Up With That? Rates of erectile dysfunction (ED) increase with age among men with the condition, 26 percent first experienced symptoms in their 50s. Research shows that the Mediterranean diet — rich in fish, nuts, vegetables and olive oil — helps, particularly for men at risk of cardiovascular disease. Making lifestyle changes like exercising and not smoking also can help.

What's Ahead: Vaginal dryness becomes more common as estrogen levels decline. But lubricants are effective, as are prescription estrogen creams and tablets.

Stop and smell the flowers. People with allergies often have less severe symptoms as they age.

Ramp Up Your Immunity

The Good News: Allergies, which result from an overreactive immune system, may become less severe, primarily because your immune system isn't as sensitive, says James Stankiewicz, M.D., chair of Otolaryngology - Head and Neck Surgery at Loyola University Medical Center in Chicago.

The Not-So-Good News: A less aggressive immune response means you're more susceptible to getting sick. Protect yourself by shedding excess pounds, eating well and exercising.

What's Up With That? Your response to vaccines decreases with age, leaving you even more vulnerable to illnesses like flu and pneumonia. You may be able to boost the effectiveness of your vaccines by getting enough sleep: A new study found that those who slept less than seven hours a night produced fewer antibodies after receiving a vaccine.

What's Ahead: At 60 you should get the shingles vaccine at 65 you'll need a shot against pneumococcal disease.

Take Fewer "Nighttime Trips"

The Good News: If you're generally healthy, your urological system likely works just about as well as it did when you were younger.

The Not-So-Good News: By their 50s, some 15 to 20 percent of people get up at least twice in the night to urinate, says Ryan P. Terlecki, M.D., assistant professor of urology at Wake Forest University School of Medicine in Winston-Salem, N.C. Try decreasing fluids after 6 p.m. and avoiding caffeinated beverages and alcohol. If you're on diuretics for high blood pressure, speak to your doctor about taking your pill in the morning. Stress incontinence — urine loss when coughing or sneezing — affects about a third of women in their 50s. It's often chalked up to vaginal deliveries and the decline of estrogen, says Terlecki, but you can reduce incontinence symptoms through training. Ask your doctor about medications and Kegel exercises, which strengthen muscles around your uterus, bladder and rectum.

What's Up With That? More than a third of men over 50 experience moderate to severe symptoms of an enlarged prostate gland, called benign prostatic hyperplasia. Symptoms include difficulty urinating, though medications like tamsulosin and finasteride can help.

What's Ahead: Urge incontinence becomes more frequent in women older than 60. More than half of men in their 70s will have prostate issues. Your best move: Stay hydrated and eat a diet rich in fruits and vegetables, which have a high water content.

Be Happy

The Good News: We get happier. A recent AARP survey showed that from your early 50s on, happiness rises significantly over time. One explanation for the trend: years of experience. "As you get older, you know that bad times are going to pass," says Laura Carstensen, Ph.D., director of the Stanford Center on Longevity. "You also know that good times will pass, which makes those good times even more precious. There's an emotional savoring that comes with age."

The Not-So-Good News: You might stay away from stressful situations, thereby missing out on new opportunities. "Older people are better at anticipating difficult situations and managing their life so they don't expose themselves to unnecessary stress," says Bob Knight, Ph.D., professor of gerontology and psychology at the USC Davis School of Gerontology in Los Angeles. While that may be good for their emotional health, it may also narrow their social networks, "limiting them to people who are more supportive."

What's Up With That? Are you worried that you're not as worried these days? "The ability to regulate one's emotions improves as you get older," says Knight. That means situations that might once have tied you up in knots no longer bother you as much. No wonder less than 5 percent of those ages 45 to 64 can expect to experience major depression.

What's Ahead: People in their 60s and 70s get progressively happier and more satisfied with their lives, according to AARP's happiness research. While 18 percent of those 61 to 65 rate themselves very happy, a full 24 percent of people 66 to 70 say the same. Studies also suggest that emotions like anger and sadness become less frequent with age, perhaps because older adults get better at tuning out negativity.

Stay Sharp

The Good News: The growth of new brain cells continues well into your 50s and 60s — and the capacity to learn new things stays strong.

The Not-So-Good News: With age comes a delay in accessing memories, but memory loss — once thought intrinsic to aging — is often avoidable, according to new research. Case in point: MRIs show that adults who exercise regularly have a bigger hippocampus (the brain region responsible for memory and learning), which helps keep the mind sharp.

What's Up With That? So you find yourself in the kitchen with no idea why you're there. Relax. In your 50s, mild forgetfulness happens because the transmission of nerve impulses between cells slows down slightly. It's rarely a sign of something serious — unless it happens every day or you never recall what you needed from the kitchen.

What's Ahead: Real cognitive decline becomes more prevalent in your 60s, and especially in your 70s and 80s. Your best prevention plan: regular exercise, intellectual stimulation and an active social life.


Thank you!

Some past research into this hypothesis concluded that blood flow to the brain does not change after a person eats a meal. But some of Kishino&rsquos recent work found that, among people who skipped breakfast, one measure of cerebral blood flow plummeted after they ate lunch. &ldquoSkipping breakfast could therefore place a heavy burden on the body after lunch by causing greater changes in [blood flow],&rdquo he says. This could lead to sleepiness.

While scientists are still figuring out exactly why food comas happen, they’ve started to home in on some factors that may contribute to post-meal fatigue.

Eating a big meal may be one trigger. Ja&rsquos research on fruit flies suggests that meal size is a &ldquostrong driver&rdquo of post-meal sleepiness. So too are meals loaded with salt or protein. But why? He says one long-held idea is that sleep somehow aids digestion. One of his not-yet-published studies&mdashagain, on fruit flies&mdashfound that sleep changes the way the insects absorbed certain macronutrients, including protein. &ldquoThis would support the idea that post-meal sleepiness affects gut nutrient absorption,&rdquo he adds.

Ja is quick to point out that his work may not translate to humans. But some of his findings&mdashlike the idea that certain foods are more likely than others to cause fatigue&mdashdovetail with some recent research on people.

A small 2018 study of truck drivers found those who ate diets rich in vegetables and fats from foods like olive oil and dairy tended to experience less post-meal sleepiness than those eating &ldquoWestern&rdquo diets heavy in processed meat, fast food and soft drinks. &ldquoOur results suggested that a healthy diet produces low sleepiness during the day,&rdquo says Claudia Moreno, one of the authors of that study and a faculty researcher at the University of São Paulo School of Public Health in Brazil. Her study points to some older research that suggests heavy fat or carbohydrate intake could potentially trigger sleepiness by disrupting the body’s natural circadian sleep rhythms.

Meanwhile, a 2018 study found that a high-fat, high-carb meal led to both sleepiness and an uptick in some inflammatory markers, especially among obese adults. But there’s still a lot of uncertainty and contradiction when it comes specific foods and their effects on post-meal fatigue. &ldquoSome human studies show an effect after eating, but others don&rsquot,&rdquo Ja says.

His research in flies, he says, helps explain why a lot of the food-coma research on humans is so inconclusive. &ldquoWe could see [the observed effects] because we used hundreds of flies and thousands of meals,&rdquo he says, &ldquobut these numbers are obviously much harder and more expensive to replicate in humans.

If you want to prevent a food coma, the best advice is to “eat smaller meals,&rdquo he says. This tactic may be especially effective at lunchtime. Predictable shifts in the body&rsquos circadian rhythms tend to make people feel drowsy in the afternoon, so if you&rsquore the type who eats a big lunch, you may be in for a double whammy.

Moreno’s research indicates that eating healthy, vegetable-centric meals could also help curb your post-meal fatigue. But the fact is, experts are still teasing out all the ins and outs of food comas.


WHO response

WHO provides support and technical assistance to national control programmes.

WHO provides the anti-trypanosome medicines free of charge to endemic countries thanks to public-private partnerships with Sanofi (pentamidine, melarsoprol, eflornithine and fexinidazole) and with Bayer HealthCare (suramin and nifurtimox). The conditioning and shipment of medicines is done in collaboration with MSF-Logistics.

In 2009, WHO set up a biological specimens bank that is available to researchers to facilitate the development of new and affordable diagnostic tools. The bank, hosted in the Institut Pasteur of Paris, contains samples of blood, serum, cerebrospinal fluid, saliva and urine from patients infected with both forms of the disease as well as samples from uninfected people from areas where the disease is endemic.

In 2008, WHO launched the initiative of the Atlas of human African Trypanosomiasis to map at village level all reported cases. This initiative is jointly implemented with FAO within the PAAT framework. The Atlas is a dynamic database including geographical and epidemiological data, compiled by WHO through the contribution of SSNCPs, NGOs and Research Institutes.

In 2014 a coordination network for human African trypanosomiasis was established under WHO leadership to ensure strengthened and sustained efforts to eliminate the disease. The stakeholders include national sleeping sickness control programmes, groups developing new tools to fight the disease, international and non-governmental organizations, and donors.
