All these divisions are arbitrary and unnatural; Bernheim's five degrees have no definite limit or line of separation one from the other, and Charcot's condition of catalepsy is only lethargy or sleep in which the subject may, to a greater or less degree, maintain the position in which he is placed by his hypnotizer.
There are, however, as already stated, two distinct and definite conditions, namely, (1) lethargy, or the inactive stage, and (2) somnambulism, or the alert stage, and if, in examining the subject, we make this simple division, we shall free it from much confusion and unnecessary verbiage.
When a subject is hypnotized by any soothing process, he first experiences a sensation of drowsiness, and then in a space of time, usually varying from two to twenty minutes, he falls into a more or less profound slumber. His breathing is full and quiet, his pulse normal; he is unconscious of his surroundings; or possibly he may be quiet, restful, indisposed to move, but having a consciousness, probably dim and imperfect, of what is going on about him.
This is the condition of lethargy, and in it most subjects, but not all, retain to a greater or less degree whatever position the hypnotizer imposes upon them; they sleep on, often maintaining what, under ordinary circumstances, would be a most uncomfortable position, for hours, motionless as a statue of bronze or stone.
If, now, he speaks of his own accord, or his magnetizer speaks to him and he replies, he is in the somnambulic or alert stage. He may open his eyes, talk in a clear and animated manner; he may walk about, and show even more intellectual acuteness and physical activity than when in his normal state, or he may merely nod assent or answer slowly to his hypnotizer's questions; still, he is in the somnambulic or alert stage of hypnotism.
The following are some of the phenomena which have been observed in this stage. It is not necessary to rehearse the stock performances of lecture-room hypnotists. While under the influence of hypnotic suggestion a lad, for instance, is made to go through the pantomime of fishing in an imaginary brook, a dignified man to canter around the stage on all fours, under the impression that he is a pony, or watch an imaginary mouse-hole in the most alert and interested manner while believing himself a cat; or the subject is made to take castor oil with every expression of delight, or reject the choicest wines with disgust, believing them to be nauseous drugs, or stagger with drunkenness under the influence of a glass of pure water, supposed to be whisky.
