The nature of hypnotic sleep has not yet been fully determined, which is not wonderful when we remember our ignorance of natural sleep. We may call the active hypnotic state a condition of excessive attention to the main idea presented and complete oblivion to other ideas. But this state is preceded by a passive condition resembling sleep. The use and value of hypnotic sleep is now occupying the attention of scientific men and it bids fair to be an important curative agent. Where once the patient suffering from insomnia was treated by drugs, he is now more successfully treated through suggestion. The change is a most desirable one and in line with that newer thought which recognizes the power of regeneration within the soul of the individual. For, the main things in the development of hypnosis and suggestion as curative agents is the recognition that an appeal can be made to the subconscious mind, which, as Dr. Worcester says, “is more sensitive to good and evil than our conscious mind.” To appeal to our latent powers to overcome our own weaknesses or limitations is greater and better than to combat these weaknesses through drugs. Many physicians who formerly employed hypnosis have adopted a substitute for it, the so-called hypnoidal state, mere passivity with closed eyes. Hypnotizing is in many cases needless and dangerous. Insomnia, like any other trouble not due to the breakdown of a physical organ, is more a moral than a material lapse, and can best be cured by moral means: that is, by the aid of the will and its associated faculties. Sleeplessness, nervousness, excitability, and irritability have their rise in mental and emotional states more often than in physical states, and, under such conditions, treatment by drugs is of little real use. In the disease hysteria, mental trouble may masquerade as physical defect, for instance paralysis or even blindness, while the physical parts concerned are in no wise impaired. The dependence placed upon merely extraneous things does not assist in the development of our own inner powers. Even when drugs seem to relieve the outward symptoms, they fail to strengthen the moral nature, so greatly in need of strength. The man of drugs only is at a disadvantage as compared with the suggestionist in treating such disorders. Dr. J. D. Quackenbos says, “The suggestionist invokes the better subliminal self—invests it with control, and seldom fails to effect the desired purpose.” He further maintains, what all investigators are now coming to admit, that, when the patient wakes from hypnotic sleep, during which helpful, curative suggestions have been made to him, he is “constrained to obey the impulses of his own superior self.” The power of suggestion, whether during waking or sleeping hours, is only beginning to be recognized, although its use in one form or another is centuries old. The thoughtless, as well as the thoughtful, use it more or less every
