Man i tell ya that paralizing/not being able to talk is what mainly gets you ain't it?
About two or so years ago i was lying in my bed and awoke to the feeling of someone gently grabbing my arm and a woman quietly saying "Daniel", i open my eyes and try to move.. Nope.. I try to scream just to see if i could, i wasn't terribly scared because i figured it was just a dream or something, nope.. If it made any noise it was like a faint gargle. It feels like 100 pounds is sitting on my whole body, i try and force myself to sit up but can't... Keep trying and then give it all my might BAM sit straight up in the bed and and feel someone let go of my arm, exactly 3AM on the clock...
Symptoms and characteristics of
Sleep Paralysis
Physiologically, sleep paralysis is closely related to the paralysis that occurs as a natural part of REM (rapid eye movement) sleep, which is known as REM atonia. Sleep paralysis occurs when the brain awakes from a REM state, but the body paralysis persists. This leaves the person fully conscious, but unable to move. The paralysis can last from several seconds to several minutes "after which the individual may experience panic symptoms and the realization that the distorted perceptions were false".[5] When there is an absence of narcolepsy, sleep paralysis is referred to as isolated sleep paralysis (ISP).[6] "ISP appears to be far more common and recurrent among blacks than among whites or Nigerian blacks",[7] and is often referred to within black communities as "the Devil on your back"[8][9]
In addition, the paralysis state may be accompanied by terrifying hallucinations (hypnopompic or hypnagogic) and an acute sense of danger.[10] Sleep paralysis is particularly frightening to the individual due to the vividness of such hallucinations.[11] The hallucinatory element to sleep paralysis makes it even more likely that someone will interpret the experience as a dream, since completely fanciful, or dream-like, objects may appear in the room alongside one's normal vision. Some scientists have proposed this condition as an explanation for alien abductions and ghostly encounters.[12] A study by Susan Blackmore and Marcus Cox of the University of the West of England supports the suggestion that reports of alien abductions are related to sleep paralysis rather than to temporal lobe lability.[13]
I have sleep paralysis pretty commonly-- well, as "commonly" as a few times a year. I've gotten used to it, and have learned to just lie there and remind myself that it will go away soon, and not to be scared. Usually my brain concludes that the person I perceive in my bedroom is a burglar who has broken into the house, but after a short bit I remind myself that it's not likely a burglar would have the ability (or inclination) to paralyze me. The first time it happened it scared the crap out of me, so I started trying to find out exactly what was going on. It's pretty neat stuff to read about.
