Hypnosis gives us a clear picture of these processes. It shows us the patient in the same state of consciousness as that in which during the war he had acquired the origin of the illness. During hypnosis the soldier relates, or once again lives through, all the things that he had experienced in former circumstances only unconsciously. We learn of distressing pains of which, when he was buried, he never became conscious. In such a hypnosis we see his anxiety displayed, his anger arise, feelings which at the moment of the excitation were benumbed and like lightning were dragged violently into the unconscious.
I can best illustrate what I have said by a few examples. For instance, the simplest cases, which occurred so often, of a flaccid paralysis of the arm after a slight gunshot wound that had been well healed for a long time and which seemed to be of a purely physical nature, showed its unconscious connections very quickly in one sitting. Consciousness only knows, “I cannot move my arm”, and no amount of reasoning was of any avail. However, the unconscious spoke during hypnosis: “In the excitement of the attack my mind became a blank. When I was hit the impact of the shrapnel was so great that my arm felt as though it was pulled violently backwards, and I immediately thought it was torn off”. The correction of the unconscious idea in hypnosis which again united the idea of the torn off arm with consciousness here quickly settled the question of an organic basis of the symptom, It can be easily understood that an arm which is no longer recognised as existing is also completely analgesic.
The neurotic symptoms which owe their origin to such suddenly occurring events we can consequently regard in their effects as realised post-hypnotic auto-suggestions. I have confirmed this view by numerous examples, I might mention the case of a soldier who suffered from a severe facial tic by which he was constantly making a grimace, and who at the same time had a contracture of the right knee joint, both of which symptoms had proved quite refractory to the usual treatment by suggestion. Hypnosis, which restored the conscious situation of the initial blowing up, very soon yielded the following information. While the patient lay unconscious under a wreckage of stones and while scenes of his native place appeared to him as in a dream, he was constantly compelled to make grimaces in order to remove the mass of sand which lay on his face and also for the purpose of breathing freely. At the same time a sharp stone was pressing on his right heel which compelled him to keep his leg bent. This compulsion which was united with unconscious ideas acted therefore as a post-hypnotic suggestion for more than a year afterwards, until at last the command which the unconscious had imposed on the patient could be annulled during hypnosis by means of my correction. In this way was the removal of these symptoms brought about. I could quote further similar examples in which these kinds of contractures represent a compulsory holding of a part in a position of ease which is based on unconscious sensations of pain.
