Sleepwalking is a disorder of consciousness that occurs between 1 and 3 hours after falling asleep and often has the following symptoms: 1. The patient involuntarily walks out of bed during sleep and then returns to bed to continue sleeping. 2. Some sleepwalkers just sit up and do not go down to the floor, and after feeling around for a while, they naturally lie down and go back to sleep. The behavior of sleepwalkers is actually purposeless, and they are unaware of their surroundings during an episode, but they can avoid all obstacles and are not dangerous or harmful to others. If a sleepwalker is not woken up by someone, he or she will go back to bed within half an hour.
