My fancy, that I am telling Professor N. that the patient whom we had both seen is suffering from a neurosis, got into the dream in the following manner. Shortly before the close of my working year I received a patient in whose case my diagnosis failed me. A serious organic affliction—perhaps some changes in the spine—was to be assumed, but could not be proved. It would have been tempting to diagnose the trouble as a neurosis, and this would have put an end to all difficulties, had it not been for the fact that the sexual anamnesis, without which I am unwilling to admit a neurosis, was so energetically denied by the patient. In my embarrassment I called to my assistance the physician whom I respect most of all men (as others do also), and to whose authority I surrender most completely. He listened to my doubts, told me he thought them justified, and then said: “Keep on observing the man, it is probably a neurosis.” Since I know that he does not share my opinions about the etiology of neuroses, I suppressed my disagreement, but I did not conceal my scepticism. A few days after I informed the patient that I did not know what to do with him, and advised him to go to some one else. Thereupon, to my great astonishment, he began to beg my pardon for having lied to me, saying that he had felt very much ashamed; and now he revealed to me just that piece of sexual etiology which I had expected, and which I found necessary for assuming the existence of a neurosis. This was a relief to me, but at the same time a humiliation; for I had to admit that my consultant, who was not disconcerted by the absence of anamnesis, had made a correct observation. I made up my mind to tell him about it when I saw him again, and to say to him that he had been in the right and I in the wrong. This is just what I do in the dream. But what sort of a wish is supposed to be fulfilled if I acknowledge that I am in the wrong? This is exactly my wish; I wish to be in the wrong with my apprehensions—that is to say, I wish that my wife whose fears I have appropriated in the dream thoughts may remain in the wrong. The subject to which the matter of being in the right or in the wrong is related in the dream is not far distant from what is really interesting to the dream thoughts. It is the same pair of alternatives of either organic or functional impairment through a woman, more properly through the sexual life—either tabetic paralysis or a neurosis—with which the manner of Lasalle’s ruin is more or less loosely connected.
