Sleepwalking is a scientific reality. It’s one of those strange phenomena that sometimes border in the fantastic. What is certain about sleepwalking is that it is a symptom of emotional disturbance, and’ that the only way to care it is to remove their worries and anxieties that eaus6 it. Doctors say that sleepwalking is much more common than is generally supposed. Many sleepwalkers do not seek help and so are never put on record, which means that an accurate count can never be made.
The questions: Is the sleepwalker actually awake or asleep Scientists have decided that he is about half--and--half. Doctors think the sleepwalker is awake in the muscular area, partially asleep in the sensory area. In other words, a person can walk in his sleep, move around, and do other things, but he does not think about what he is doing.

To protect themselves, some sleepwalkers have been known to tie themselves in bed, lock their doors, hide the keys, bolt the window, and take all sorts of measures to wake themselves if they should get out of bed. Curiously enough, they have an unusual way of avoiding their own traps when they sleepwalk, so none of their tricks seem to work very well. Some sleepwalkers talk in their sleep loudly enough to wake someone else in the family who can then shake them back to their senses.
Children who walk in their sleep usually outgrow the habit. In many adults, too, the condition is more or less temporary. If it happens often, the sleepwalker should seek help. Although sleepwalking itself is nothing to become alarmed about, the problems that cause the sleepwalking may be very serious.
