Sleep paralysis is a temporary inability to move or speak that occurs when you're waking up or falling asleep. It's not harmful and should pass in a few seconds or minutes, but can be very frightening.
Sleep paralysis happens when parts of rapid eye movement (REM) sleep occur while you're awake. REM is a stage of sleep when the brain is very active and dreams often occur. The body is unable to move, apart from the eyes and muscles used in breathing, possibly to stop you acting out your dreams and hurting yourself.
