Parasomnias include a range of unwanted behaviors or experiences that occur during sleep. They are classified by the type of sleep from which they occur. These two types are rapid eye movement (REM) and non-REM sleep.


Non-REM parasomnias include sleepwalking, sleep terrors (also called night terrors) and sleep eating. A common REM parasomnia is REM sleep behavior disorder (RBD). In RBD, the body is not able to suppress movements during dreaming (REM) sleep. When this occurs, people act out their dreams, which can be problematic because people often kick, punch and/or shout during these episodes. Treatments differ across parasomnias and are tailored to individuals’ specific symptoms, contributing factors and type of parasomnia.
