Parasomnias are adverse events that either occur during sleep or are exaggerated by sleep. Many of these disorders are considered to be disorders of partial arousal from various sleep stages. Examples of parasomnias are sleepwalking disorder, sleep terror disorder, and nightmare disorder. 

Non-REM parasomnias have variable prevalence rates depending on patient age and different diagnoses. Sleep talking, brux-ism, sleepwalking, sleep terrors, and enuresis occur more frequently in childhood than in adulthood. Nightmares appear to occur with similar frequency in adults and children.

We don t understand why, in some cases, the trauma is almost always dominant and, in others, it has such a small role to play in the shaping of dreams. One answer may be that victims of trauma, e.g. post-traumatic stress disorder patients who have had violent experiences in war, have a specific kind of awakening experience. Their sleep is interrupted by terrors akin to the night terrors of children, and, like in the night terrors of children, these do not occur in REM sleep when normal dreaming takes place. Instead, they occur in NREM sleep, the phase of sleep in which the brain is less completely activated, but in which powerful emotions can nevertheless make themselves felt.
