Has anyone ever experienced sleep paralysis?
(taken from http://en.wikipedia.org/wiki/Sleep_paralysis)
Sleep paralysis is a condition characterized by temporary paralysis of the body shortly after waking up (known as hypnopompic paralysis) or, less often, shortly before falling asleep (known as hypnagogic paralysis).
The Nightmare, by Henry Fuseli (1781) is thought to be one of the classic depictions of sleep paralysis perceived as a demonic visitation.
Physiologically, it is closely related to the normal paralysis that occurs during REM (rapid eye movement) sleep, also known as REM atonia. Sleep paralysis occurs when the brain is awakened from an REM state into essentially a normal fully awake state, but the bodily paralysis is still occurring. This causes the person to be fully aware, but unable to move. In addition, this state may be accompanied by hypnagogic hallucinations.
More often than not, sleep paralysis is believed by the person affected by it to be no more than a dream. This is the reason why there are many dream recountings which describe the person lying frozen and unable to move. The hallucinatory element to sleep paralysis makes it even more likely that someone will interpret the experience as simply a dream, as one might see completely fanciful objects in a room alongside the normal vision one can see.
Symptoms:
The primary symptom of sleep paralysis is conscious partial or complete skeletal muscle paralysis during the hypnopompic or hypnagogic states. In other words, it is the sense of being aware that one is unable to move or speak while falling asleep or waking up. Sleep paralysis may also be [citations needed] accompanied by hypnagogic hallucinations. These hallucinations can be auditory, tactile, and/or visual. If a polysomnography is taken, at least one of the following will be shown: skeletal muscle tone suppression, REM sleep at sleep onset, or dissociated REM sleep. The sleep paralysis persists anywhere from a few seconds to a few minutes [citation needed] before the person is able to either return to REM sleep or to become fully awake. However, the sense of how much time has gone by is often distorted during sleep paralysis. People who are fortunate enough to be facing a clock while having an episode may often be surprised to see how little time has gone by during an episode that seems to last a long time.[citation needed] Although severe sufferers can experience a sleep paralysis that may last for several hours.[citations needed]
