REM Behavior Disorder
REM Behavior Disorder is a potentially dangerous sleep disorder characterized by uncontrollable movements and actions during REM stage sleep. Normally, the body is temporally paralyzed during REM, but not in people with REM behavior disorder. They end up acting out their dreams. Some may walk, talk, scream, hit, or punch in their sleep. Sufferers are at risk for injuring themselves and others, especially if they are acting out a violent dream. REM behavior disorder usually affects men and can be successfully treated with medication.
