In this state of negative repose there is no manifestation of thought, and it is as unlike the clairvoyant or sensitive state as that of wakefulness; but shaded into this state of sleep, as into that of wakefulness, are various degrees of sensitiveness. The conditions of sleep are provocative of this impressibleness. Night is negative; the silence and the vail of darkness shutting out external objects conduce to make the mind negative and susceptible.

At midnight is the culmination of this negativeness, and hence the ghastly dread of that hour has a foundation in fact, and is not an idle superstition. Ghosts may never appear, yet if they were to appear the midnight hour, of all others, would be assigned by the student cognizant of this fact for them to come like shafts of frozen moonshine, into the walks of men.

Mesmeric State.—Mesmerism, under whatever name, animal magnetism, hypnotism, etc., is a potent means in the study of psychology. It has made it possible to command many of the most evanescent phenomena, and allow of their careful examination, when otherwise they came at rare intervals and at such unexpected moments as made it impossible to carefully compare and study them. Somnambulism, clairvoyance, and that state of exquisite sensitiveness which makes us receptive of impressions transformed into dreams, may be commanded in a sensitive, and observed at leisure.

In the commencement we must free ourselves from the commonly received idea that sleep has any resemblance to any of these several states which are usually called magnetic, mesmeric, or clairvoyant sleep. As already stated, sleep is the negative of being, and more distinct from these states of exalted perception than waking. The incongruous and often incoherent visions which arise in the half-waking state, or when only a part of the mental faculties are at rest, are the ordinary dreams, which have no significance, and are very different in their origin and meaning from the impressions received in the sensitive state, which is one of intense wakefulness and activity. The sensitive condition is possessed in a marked degree by about one in five, and may be induced in a still larger ratio. It is more frequently found in women than in men. It may be cultivated, and become an important factor in the character and happiness of the individual.

We will simply for convenience divide the sensitive state into the hypnotic, somnambulic and clairvoyant; but it must be borne in mind that these merge into each other; and that no sharp line can be drawn between them.

Mesmerism may be regarded as the method by which all of these states may be induced. The mesmeric state is equivalent to the hypnotic. After years of delay, mesmerism has been accepted under another name, that of hypnotism; but the theory of a “fluid” or specific influence is discarded. Hypnotists cannot, however, exceed the most common experiments without the facts demanding even as a working hypothesis, this specific influence.

The ticking of a watch held close to the ear, or intensely gazing at some object, will throw a sensitive into an abnormal condition, at the mercy of the “dominant idea,” and he becomes an automaton in the hands of an external influence. This is the hypnotic state, beyond which the “dominant idea” fails. A sensitive may be led by a “dominant idea,” but soon manifests a power which stretches beyond into an unexplored region of possibilities, exhibiting mental perceptions far more acute than those possess who are around him, or he himself possesses in his normal condition. Hypnotism as treated by its exponents is an extremely complicated state, ranging from the cataleptic to the independent clairvoyant. To define it with the usual narrow meaning is extremely misleading and unscientific.

There are two distinct states of hypnotism. The first is that in which most platform experiments are made. The sensitive is capable of carrying on conversations, answering questions, and is governed by a “dominant idea,” believing all the operator wishes, and doing as commanded.

The sensitive rapidly enters the next stage, when he becomes insensible to pain, and irresponsive to the address of any one except the operator. Until this stage is reached consciousness and memory are retained, a fact fatal to the theory of automatic action or “unconscious cerebration.” In this profound state the sensitive has no memory of events which occur. It is an induced, incipient somnambulism, the true counterpart of that which under proper condition appears spontaneously.

The report of the Committee on Hypnotism, vol. I., p. 95, of Proceedings of American Society for Psychical Research, shows that it confined its attention to fifty or sixty students of Harvard College. Of these about a dozen were affected, and of these, two were so good that attention was confined to them.
