One in four people is a sleepwalker. Whereas the cause of sleepwalking in children is usually unknown, possible causes of sleepwalking in adults are alcohol, sedatives and mental disorders.

What happens when you sleepwalk?

Sleepwalking (somnambulism) happens during the deep sleep phase. Sleepwalkers get out of bed and perform usual daily tasks. It’s difficult to wake them at the time and they can't remember what happened after the event. Sleepwalkers can injure themselves or others.

Take a look at this video of a mother who was caught on video by her son while she was sleepwalking.
