Abstract

It is not sufficiently realised that sleep-walking is not an hysterical condition, nor in any way related to epilepsy, nor that it can be accompanied by violent injury to the self or others. Three case reports here include that of a 14-year-old boy who rose from his bed at 2 a.m. and severely stabbed his five-year-old girl cousin. The sleeping mind is not in touch with reality and amnesia for events during sleep is usual.
