In plunging the patient into the hypnoidal state, we have him revert to a primitive rest-state with its consequent beneficial results. The suggestibility of the state, if skillfully handled, is apt to increase the therapeutic efficacy. Relaxation of nervous strain, rest from worry, abatement of emotional excitement are known to be of great help in the treatment of nervous troubles of the neurasthenic, or of the so-called “psychoasthenic” variety. That is what we precisely observe in the treatment of psychopathic or neurotic diseases by means of the agency of the hypnoidal state, the efficacy of which is all the greater on account of the presence of the important trait of suggestibility. The most important fact, however, is _the access gained through the hypnoidal state to the patient’s stores of subconscious reserve neuron energy, thus helping to bring about an association of disintegrated, dissociated mental-systems_. Dr. John Donley in his article, “The Clinical Use of Hypnoidization” (_Journal of Abnormal Psychology for August-September, 1908_), gives the following account of the method of hypnoidization: “The treatment of that large group of disorders, forgotten memories, and emotions is operative in the production of mental disaggregation, but also in those numerous instances where the experience causing the obsessive idea or emotion is well known to the upper consciousness. “In hypnoidal states they were made to reproduce their obsessive thoughts and images and then to describe them in words. When this had been accomplished and they had received further assurance and persuasion from the experimenter, although the purely intellectual content of their obsessions remained known to them, the insistent automatic character and disturbing emotional factors had disappeared. In this metamorphosis of emotional reaction we may observe one of the most interesting and useful attributes of the hypnoidal state.” Dr. Donley gives a series of cases which he treated successfully from psychognostic and psychotherapeutic standpoints. The reader is referred to the original article. “The value of hypnoidization,” says Dr. T. W. Mitchell, “in the resurrection of dissociated memories is that which is perhaps best established. And this applies not only to the restoration of the forgotten experiences of ordinary amnesia, but to the recovery of dissociated memories that are of pathogenic significance.... Sidis himself has insistently taught that the reassociation of dissociated complexes effects a cure of psychopathic disease.... My own experience, so far as it goes, tends to corroborate in every respect the claims put forward by Sidis....”
