Sleepwalking is a disorder that causes people to get up and walk while they're asleep. It usually happens when a person is going from the deep stage of sleep to a lighter stage or into the awake state. The sleepwalker can't respond during the event and usually doesn't remember it. In some cases, he may talk and not make sense.
When someone sleepwalks, they might quietly walk around their room. Or they might run or attempt to "escape." Typically, the sleepwalker's eyes are open with a glassy stare as he roams the house. If you question him, he'll be slow to respond or not respond at all. When you get him back to bed without waking him up, he usually won't recall the event. Older children may wake up more easily at the end of a sleepwalking episode.
Seventy-one percent of the patients reported at least 1 dreamlike mentation associated with the sleepwalking/sleep terrors episode. The dreamlike mentation action corresponded with the observed behavior. A total of 106 dreamlike mentations were collected (mean: 3 ± 3.4 dreamlike mentations/patient, range 0-17). Most (95%) dreamlike mentations consisted of a single visual scene. These dreamlike mentations were frequently unpleasant, with aggression in 24% (the dreamer being always the victim), misfortune in 54%, and apprehension in 84%. The patients with dream mentations reported more severe daytime sleepiness.
