4.11 : 梦游和梦话

Sleepwalking, also known as somnambulism, occurs during stages 3 and 4 of deep sleep when individuals are least likely to be dreaming.

During sleepwalking episodes, individuals often have their eyes open but are unresponsive and typically do not recall these events.

Common triggers for sleepwalking include sleep deprivation and alcohol consumption. For example, staying up late for a work deadline or drinking at a party may increase risks.

It is generally safe to direct a sleepwalker to prevent potential injuries, such as tripping in a dark room.

Another unusual nocturnal behavior is sleep talking, also known as somniloquy, which involves speaking during sleep without awareness or accurate memory of the conversation.

Individuals might appear to respond to questions, but their answers are generally unreliable.

Ambien, a medication used to treat sleep disorders, has unusual side effects, such as sleep eating, which occurs when users unconsciously eat while asleep, often finding unexpected food wrappers or missing food items upon waking.
