Term: Night terror
Definition (Myers): A sleep disorder characterized by high arousal and an appearance of being terrified.
Definition (alternative): A night terror, also known as pavor nocturnus, is a parasomnia disorder characterized by extreme terror and a temporary inability to regain full consciousness. http://en.wikipedia.org/wiki/Night_terror
Contextual explanation: The subject wakes abruptly from slow-wave sleep, with waking usually accompanied by gasping, moaning, or screaming. It is often impossible to fully awaken the person, and after the episode the subject normally settles back to sleep without waking. A night terror can rarely be recalled by the subject. The lack of a dream itself leaves those awakened from a night terror in a state of disorientation much more severe than that caused by a normal nightmare. This can include a short period of amnesia during which the subjects may be unable to recall their names, locations, ages, or any other identifying features of themselves.
