sleepwalking

 
rising from bed and walking or performing other complex motor behavior during an apparent state of sleep; much mystery has been attached to this, although it is no more mysterious than dreaming. The chief difference between the two is that the sleepwalker, besides dreaming, is also using the part of the brain that stimulates walking. This usually occurs during the first third of the night and lasts for a few minutes to a half hour. The sleeper is relatively unresponsive, not easily awakened, and usually amnesic for the episode later. It is most likely to happen during periods of emotional stress and usually ceases when the source of anxiety is removed. In many cases it occurs only once or twice and does not happen again. If it recurs frequently (called sleepwalking disorder) it may stem from serious emotional distress (see sleep disorders). Called also somnambulism.
sleepwalking disorder repeated episodes of sleepwalking.

sleepwalking

A state of dissociated sleeping and waking common in children, especially boys, and lasting usually for only a few minutes, in which the child gets out of bed and moves about. Sleepwalking in childhood is never purposeful and is of little importance so long as danger from falls is avoided. The child should be guided gently back to bed. Sleepwalking in adults usually has a hysterical basis.
