Sleep Paralysis is the temporary inability to move, after awakening from a dream, or possibly before even falling asleep. The condition arises when the brain awakens from REM sleep while the body remains immobilised. In this state the sufferer may experience vivid nightmares, which are seemingly real, and as such highly distressing.
