The experiment was repeated on other subjects, in all cases with the same result. Only one knew that the music was the “Ride of Walkure.” “To him it always expressed the pictured wild ride of the daughters of Wotan, the subject taking part in the ride.” It was noticeable in each case that the same music played to them in the waking state produced no special impression. Here is incontestable evidence that in the hypnotic state the perception of the special senses is enormously heightened. A slow movement was tried (the Valhalla motif). At first it seemed to produce the opposite effect, for the pulse was lowered. Later it rose to a rate double the normal, and the tension was diminished. The impression described by the subject afterward was a feeling of “lofty grandeur and calmness.” A mountain climbing experience of years before was recalled, and the subject seemed to contemplate a landscape of “lofty grandeur.” A different sort of music was played (the intense and ghastly scene in which Brunhilde appears to summon Sigmund to Valhalla). Immediately a marked change took place in the pulse. It became slow and irregular, and very small. The respiration decreased almost to gasping, the face grew pale, and a cold perspiration broke out. Readers who are especially interested in this subject will find descriptions of many other interesting experiments in the same article. Dr. Cocke describes a peculiar trick he played upon the sight of a subject. Says he: “I once hypnotized a man and made him read all of his a’s as w’s, his u’s as v’s, and his b’s as x’s. I added suggestion after suggestion so rapidly that it would have been impossible for him to have remembered simply what I said and call the letters as I directed. Stimulation was, in this case impossible, as I made him read fifteen or twenty pages, he calling the letters as suggested each time they occurred.” The extraordinary heightening of the sense perceptions has an important bearing on the question of spiritualism and clairvoyance. If the powers of the mind are so enormously increased, all that is required of a very sensitive and easily hypnotized person is to hypnotize him or herself, when he will be able to read thoughts and remember or perceive facts hidden to the ordinary perception. In this connection the reader is referred to the confession of Mrs. Piper, the famous medium of the American branch of the Psychical Research Society. The confession will be found printed in full at the close of this book. CHAPTER V.
