Parasomnias
Parasomnias are unpleasant feelings or behaviors that take place during the night when non-dream or non-REM sleep is taking place. This usually happens within the first two hours of sleep onset and includes Confusional arousals where there is an abrupt partial awakening from sleep manifested by disorientation, slow speech confusion and amnesia for the event upon full awakening. Sleepwalking and sleeptalking are other examples of parasomnias. More disturbing is the parasomnia known as sleep terrors which are more frightening than dreams or nightmares and include crying out, feelings of extreme anxiety and impending doom. These disorders are common during childhood and generally disappear during the teenage years. They rarely require treatment but sometimes medication is used if the parasomnia causes the person to place themselves in harm's way.
