Facts About Sleep Paralysis That Not Everyone Knows
Update: 17/09/2015
To discover more about the phenomenon of incubus and the feeling of awakening but something heavy on your chest that you could not get up.
There should be had once you woke up between night and felt like something heavy on your chest. You wanted to open your eyes, cry for help or move your limbs, but apparently they all became powerless?
You thought that Death has come and been awaiting you to go? The truth was, you were experiencing the frightening feeling of sleep called incubus.
1. It feels kind of like you woke up dead.
“Most patients say the same thing to describe sleep paralysis: that it feels like you woke up dead. You know that your mind is awake and your body is not — so you’re trapped, essentially,†Michael Breus, Ph.D., clinical psychologist and fellow of the American Academy of Sleep Medicine, tells BuzzFeed Life.
2. And it’s way more complicated than a nightmare.
“It is the complete opposite, actually,†Breus explains. When you enter deep REM sleep, your brain tells the body’s voluntary muscles to relax and go into almost a state of paralysis, which is called atonia. Atonia actually helps protect the body from injury by preventing you from acting out the physical movements in your dreams. In other parasomnias, such as sleepwalking or REM sleep behavior disorder, atonia does not occur properly and the voluntary muscles move while the mind remains asleep, which is why people can sometimesdo crazy things in their sleep and be totally unaware of it.
In sleep paralysis, the body remains paralyzed in REM atonia while the brain awakens and the eyes start to open, explains Breus. Sufferers become alert in a transient conscious state, but they are unable to move voluntary muscles or speak. Although involuntary muscle movement, like breathing, is not affected, there is often a sensation of chest pressure, which is why many people wake up from sleep paralysis gasping to take a deep breath. Episodes can last anywhere from 20 seconds to a few minutes.
3. Sleep paralysis can involve hallucinations.
Unlike the visuals in nightmares or lucid dreams, which occur when the eyes are closed in REM sleep, these hallucinations occur in the state between sleeping and waking when the mind is alert and the eyes are open. True visual and auditory hallucinations during sleep paralysis are relatively rare, according to Breus, but many patients report feeling an undeniably strange or scary presence in the room.
Plus, sleep paralysis is just super frightening to begin with, so it often triggers a panicked response with increased heart rate. “People freak out because they can’t move, and it’s this extreme anxiety which causes people to be very fearful of their surroundings,†says Breus.
4. You can’t just wake yourself up.
Some patients report that they can wiggle their toes, fingers, or facial muscles, which helps them wake up the rest of their body.
“Everybody tries something different, but you can’t fool mother nature — there’s no way to pull yourself out of it. You just have to wait it out,†says Breus. A Penn State study found the highest prevalence rates were in students and psychiatric patients.
5. Sleep paralysis is actually a natural occurrence and can happen to anyone.
Every time you go to sleep, there is some risk of waking up in sleep paralysis, says Breus. But severity and degree of consciousness vary greatly — most people have at least one episode at some point in life but aren’t even aware of it. When it does happen, it’s highly individual and rarely the same experience for everyone.
…But it’s most common among young adults and people with a history of mental illness.
6. It’s probably related to being sleep deprived.
According to Breus, research has consistently shown that the less sleep you get and the more exhausted you are, the more likely you are to experience sleep paralysis and other sleep disorders.
So avoiding sleep paralysis might be as simple as getting better and longer sleep.
If you consume large amounts of alcohol, it prevents you from entering deeper stages of sleep which decreases the quality.â€
So if sleep paralysis is something you deal with, make sure you’re getting enough sleep and you’re not doing things that compromise the quality of your sleep (like drinking a lot or eating right before bed
7. But really, there is no definitive cause.
Stress, depression, certain prescription medications, and, more recently, an inherited gene have all been linked to sleep paralysis, Breus tells us. But while research shows associations, there is no clear cause of sleep paralysis, which is obviously super frustrating for anyone going through this.
We do know that sleep paralysis can either occur on its own as an isolated incident, or it can be a symptom of other sleep disorders, such as narcolepsy. And there’s no explanation for why it might happen every other day or just every once in a while.
Accounts of sleep paralysis can be found in Persian medical texts dating back to the 10th century. The first clinical observation was made by a Dutch physician in 1664 who diagnosed a 50-year-old woman with “Night-Mare.†It was believed to be caused by demons or spiritual possession until the 19th century, when it was termed “sleep palsy†and eventually “sleep paralysis†in medical texts.
8. However, there’s really no evidence that it’ll kill you.
“Research has shown that sleep paralysis is not dangerous,†says Breus. “It does not cause physical harm to the body and there are no clinical deaths known to date.†While there are some terrifying cultural explanations around the world, these are constructed to make sense of a very mysterious condition.
“The biggest thing is to educate people to not be afraid,†says Breus. “In all likelihood, they just need more rest and enough sleep
