That this is more than a mere metaphor has been proved by Professor Freud and others of the Vienna school, who cure cases of hysteria by inducing the patient to give expression to the secret anxieties and emotions which, unknown to him, have been preying upon his mind. The clue to these disturbing thoughts is generally obtained in dreams or similar states of relaxed consciousness. According to the Freudians a dream always means something, but never what it appears to mean. It is symbolic and expresses desires or fears which we refuse ordinarily to admit to consciousness, either because they are painful or because they are repugnant to our moral nature. A watchman is stationed at the gate of consciousness to keep them back, but sometimes these unwelcome intruders slip past him in disguise. In the hands of fanatical Freudians this theory has developed the wildest extravagancies, and the voluminous literature of psycho-analysis contains much that seems to the layman quite as absurd as the stuff which fills the twenty-five cent dream book. It is impossible to believe that the subconsciousness of every one of us contains nothing but the foul and monstrous specimens which they dredge up from the mental depths of their neuropathic patients and exhibit with such pride. Bergson's view seems to me truer as it is certainly more agreeable, that we keep stored away somewhere all our memories, the good as well as the evil, the pleasant together with the unpleasant. There may be nightmares down cellar, as we thought as a child, but even in those days we knew how to dodge them when we went after apples; that is, take down a light and slam the door quickly on coming up. Maeterlinck, too, knew this trick of our childhood. When in the Palace of Night scene of his fairy play, the redoubtable Tyltyl unlocks the cage where are confined the nightmares and all other evil imaginings, he shuts the door in time to keep them in and then opens another revealing a lovely garden full of blue birds, which, though they fade and die when brought into the light of common day, yet encourage him to continue his search for the Blue Bird that never fades, but lives everlastingly. The new science of dreams is giving a deeper significance to the trite wish of "Good night and pleasant dreams!" It means sweet sanity and mental health, pure thoughts and good will to all men.
