When put into hypnosis, however, the memory assumes a different character. She is taken back in imagination to the scene of the accident. Once more the train is entering the station; she leaves the car, steps from the platform upon a truck; then, unawares, steps off the truck and falls to the ground. As she falls her face suddenly becomes distorted with fear; tears stream down her cheeks, which become suffused; her heart palpitates; she suffers again acute pain in her arm, and so on. Her physical and mental anguish is painful to look upon. Though I try to persuade her that she is not hurt and that the accident is a delusion my effort is not very successful. In this experiment, as in the others, there is substantially a reproduction in all its details of the content of consciousness which obtained at the time of the accident, and also of the emotion and its physiological manifestations—all were faithfully conserved. Further, each event follows in the same chronological sequence as in the original experience. But in these observations the reproduction differs somewhat from that of ordinary memory. It is in the form of a dream, hypnotic or normal, and the subject goes back to the time of the experience, which he thinks is the present, and actually lives over again the original episode. Unlike the conditions of ordinary memory the whole content of his consciousness is practically limited to that which originally was present, all else, the present and the intervening past, being dissociated and excluded. The original psychological processes and their psycho-physiological accompaniments (pain, paralysis, anesthesia, spasms, etc.) repeat themselves as if the present were the past. Plainly, for such a reproduction, the original episode must have left conserved dispositions of some kind which when excited were capable of reënacting the episode in all its psycho-physiological details. From a consideration of such phenomena it is easy to understand how certain psycho-neuroses may be properly regarded as memories of certain past experiences. The experiences are conserved and under certain conditions reproduced from time to time.
