Sleepwalking is a complex disorder where individuals can perform activities, such as cooking or studying, while in a state of unconsciousness, often without any memory of the event afterward. This phenomenon occurs because certain brain functions remain active while others, particularly those related to memory storage and recall, may not be fully engaged. As a result, sleepwalkers can navigate their environment and perform tasks, yet they do not retain memories of these actions. The discussion highlights the potential dangers of sleepwalking, as it can lead to hazardous situations, emphasizing the importance of understanding this disorder.
