2. Sleeping and Waking Life in Relation to the Planets

But some people have yet a third kind of sleep. Although this third kind occurs only rarely, everyone knows that it does occur; it is when a man begins to talk or act in sleep without the consciousness that is his in waking life. Usually he knows nothing the next day of the impulses which have driven him to such actions during sleep. The condition can be enhanced to the point of what is usually called sleepwalking. While he is walking in his sleep a man may also have certain dreams; but it is not so in the majority of cases; in a certain sense he acts like an automaton, impelled by obscure urges of which he need not have even the consciousness of dream. Through this third influence he enters into contact with the outer world as he does by day, only now he is unconscious. Such actions in sleep are therefore subject to a third influence.
