my friend sometimes feels something while sleeping?

Question

he wakes up and finds that someone is trying to press him down to the bed but he cannot see them then he sees something like ghosts he cannot move a muscle can somebody give scientific explanation pls

Answer 1

We are paralyzed when we sleep. If they were not we would sleep walk all the time. Maybe he is kind of half-sleeping; still paralyzed from sleep, but awake so he can see things around him.
The ghosts he sees indicate that he dreams, or that he is so terrified that he imagine things.

Answer 2

Sleep paralysis occurs during REM sleep in order to prevent the body from manifesting the sleeper's dreams. Little is known about the physiology of sleep paralysis. However, some have suggested that it may be linked to post-synaptic inhibition of motor neurons in the pons region of the brain. In particular, low levels of melatonin may stop the depolarization current in the nerves, which prevents the stimulation of the muscles, to prevent the body from enacting the dreamt activity (ie. preventing a sleeper from running when dreaming about running.)

There is also a significant positive correlation between those experiencing this disorder frequently and those suffering from narcolepsy. However, various studies suggest that many or most people will experience sleep paralysis at least once or twice in their lives.

Some report that various factors increase the likelihood of both paralysis and hallucinations. These include:
Sleeping in a supine position (facing upwards)
Irregular sleeping schedules; naps, sleeping in, sleep deprivation
Increased stress
Sudden environmental/lifestyle changes
A lucid dream that immediately precedes the episode. Also conscious induction of sleep paralysis is a common technique to enter a state of lucid dreams.

Scientific? I won't give you a scientific explaination but you can read the wiki below on sleep paralysis.

He is obviously being visited by aliens, ghosts, the old hag and succubi. I've had it once when I fell asleep on my back. Interesting sensation.

Answer 4

There's this moment before you fall asleep that you're conscious but can't move a muscle. It also can cause you to imagine things that aren't there. I don't remember what it's called in scientific language, but if you do a little research you'll find it.

Answer 5

Its called a hag if he sleeps on his back then the hag comes and rides his back they say it does this when someones mad at you or if you did something bad u know you werent supossed to do but thats what they say.althught it does sound like he has the symtoms because they say shes a spirit and you cant move or talk while this is going on

Answer 6

Sometimes I feel like when I'm Sleeping that when I come out of a dream it feels like I'm am falling, sometimes I'll even fall off my bed...Good luck with an answer though.

Answer 7

Schizophrenia/Hallucenations

Answer 8

Sometimes when you are sleeping you become partially but not fully awake. You can actually hear conversations sometimes, yet you can't move you muscles because that part of your brain hasn't become active yet.

Answer 9

maybe it's all the artificial waves (television, radio, cellular, electromagnetic pollution.. ) in the atmosphere preventing your friend from consciously going out of their body.

Answer 10

poltergeists or terrors,both are acused by infrailty in minds, something you did terribly wrong or something you shouldn't have done at all, they mostly hang in your fears, attracted by self doubt and faded hopes, or a dead memory.
