The following experiment is now made. By suggestion in hypnosis he is made to believe that he is fifteen years of age. As a consequence in his hypnotic dream he is once more living in Russia before he had learned English. It is now found that he has spontaneously lost all knowledge of the English language and can speak only Russian. He is told it is the night of the ball and, as in a dream, he is carried successively through the different events of that night. Finally he returns in search of the ring, passes again over the lonely road, hears the footsteps and becomes frightened. At this point his face is suddenly contorted with an expression of fright, the whole right side becomes paralyzed and anesthetic, and the muscles of face, arm, and leg affected with clonic spasms. At the same time he moans with pain which he experiences in his side, which he hurt when he fell. Though consciousness is confused he answers questions and describes the pain which he feels. On being awakened all passes off. Mrs. W. on her return to Boston after an absence in Europe happened to pass by a certain house on her way to her hotel; the house (a private hospital) was one with which she had very distressing associations. On leaving the steamer she took a street car which she left a block distant from the hotel. She walked this distance and as she passed the house she was seized with a sudden attack of fear, dizziness, palpitation, etc. Although it is beside the point I may say that she had not noticed the locality and did not consciously recognize the house until the attack developed. The attack was, therefore, induced by a subconscious perception.[15] She recalls the incident and describes the attack, remembers that it occurred at this particular spot, but without further detail. Now in hypnosis she is taken back to the day of her arrival on the steamship. In imagination, as in a sort of dream, she is living over again that day; she disembarks from the ship, enters the street car in which she rides a certain distance; she leaves the car at the point nearest her destination and proceeds to walk the remainder of the distance; suddenly her face exhibits the liveliest emotion; she becomes strongly agitated and her respiration is short and quick; her head and eyes turn toward the left and upward, as if in search of a cause, and she exclaims, “Yes, that’s it, that’s it,” as she recognizes in imagination the house which had been the scene of her previous distress. Then the attack subsides as she passes by, continuing her way toward her hotel. Mrs. E. B. suffers from traumatic hysteria as the result of a slight but emotional accident—a fall—when alighting from a railway train. The accident resulted in a sprained shoulder and neuritis of the arm. She fully remembers the accident and describes it as any one might.
