Sleepwalking is most common in children, who usually outgrow it by their teens.

Sleepwalking usually occurs one to two hours after falling asleep at night. Rarely, it may involve unusual behaviors, such as climbing out a window or urinating in a closet.

Often, sleepwalking is a random, harmless event. Treatment may be needed if it occurs often or causes injury. Medications and hypnosis may help.
