Somnambulism (Sleep Walking)

Episodes of nocturnal walking about, varying in duration, during which the subject is asleep or at least incompletely awake. Following awakening the subject has no memory of the preceding events. Although they are generally inattentive to any efforts to gain their attention, somnambulists may execute very complex acts, such as dusting or going to the toilet.4
