text: not sure but maybe your talking about sleep paralysis: you kinda feel like you're awake but you can't move or that you might fall or you try to speak but you can't sorta like you're frozen awake---maybe that wiki thing has something -- http://en.wikipedia.org/wiki/Sleep_paralysis Sleep paralysis is a condition characterized by paralysis of the body shortly after waking up (known as hypnopompic paralysis) or, less often, shortly before falling asleep (known as hypnagogic paralysis). Physiologically, it is closely related to the normal paralysis that occurs during REM sleep, also known as REM atonia.\n\n \nThe Nightmare, by Henry Fuseli (1781) is thought to be one of the classic depictions of sleep paralysis perceived as a demonic visitation.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 is usually accompanied by certain specific kinds of hallucinations. This state usually lasts no more than two minutes before a person is able to either return to full REM sleep or to become fully awake,(more in the article but I didn't want the post to be too long.)  Thanks :-)
