<unk>  (also called somnambulism or noctambulism), under the larger category of parasomnias or sleep disorders where the sufferer engages in activities that are normally associated with wakefulness while he or she is asleep or in a sleeplike state.<unk>  is usually defined by, or involves the person affected apparently shifting from his or her prior sleeping position and moving around and performing normal actions as if awake (cleaning, walking and other activities). Sleepwalkers are not conscious of their actions on a level where memory of the<unk>  episode can be recalled, and because of this, unless the sleepwalker is woken or aroused by someone else, this sleep disorder can go unnoticed.<unk>  is more commonly experienced in people with high levels of stress, anxiety or other psychological factors and in people with genetic factors (family history) or sometimes a combination of both.
A common misconception is that<unk>  is an individual acting out the physical movements within a dream, but in fact<unk>  occurs earlier on in the night when rapid eye movement (REM), or the "dream stage" of sleep, has not yet occurred.
