This Parasomnia is characterized by recurrent episodes in which the individual abruptly awakens with a cry of terror, autonomic arousal, and other fear behavior. They may not respond readily to efforts to comfort or awaken them fully. If they do awaken they have limited recollection of dream material, but they are completely amnesic for the event the following morning.
