Rumor: Don't wake up sleepwalkers, or they'll become stupid, dumb, psychotic, and possibly scared to death.
Sleepwalking is just a type of sleep disorder
The Fact: Sleepwalking, a magical phenomenon for ordinary people, is actually just a type of sleep disorder. For most sleepwalkers, what they do during sleepwalking is normal behavior, such as getting up and sitting on the bed, getting dressed, and moving around the room. Only a few sleepwalkers perform complex movements, such as boiling water, cooking, going out, driving, etc.
Just confused about the situation
In fact, waking up a sleepwalker is not an easy task. Sleepwalkers are in stages 3 and 4 of non-rapid eye movement sleep, a state of deep sleep, and normal volume and contact will not wake them up. Even if awakened, he won't go crazy, he's just confused about his situation and a little scared. [1] Because sleepwalkers have no memory of everything that happened during sleepwalking, who would not be surprised to find that they were not in bed, but suddenly appeared in the living room, kitchen, or even an unfamiliar place after waking up! As for frightening people to death, it is estimated that it is only possible for people with extremely fragile hearts.
Conclusion
Rumors busted. Awakening a sleepwalker will not cause harm, the person will just be confused, but it is recommended not to wake him up and gently guide him back to bed to continue sleeping.
