Sometimes the resistances are of a more serious character. For instance, persons who cannot admit certain morally grave sides to their characters, project their deficiencies upon the doctor by calmly presuming that he is more or less deficient morally, and that for this reason they cannot communicate certain unpleasant things to him. If, then a patient does not dream from the beginning or ceases to dream he retains material which is susceptible of conscious elaboration. Here the personal relation between the doctor and his patient may be regarded as the chief hindrance. It can prevent them both, the doctor as well as the patient, from seeing the situation clearly. We must not forget that, as the doctor shows, and must show, a searching interest in the psychology of his patient, so, too, the patient, if he has an active mind, gains some familiarity with the psychology of the doctor and assumes a corresponding attitude towards him. Thus the doctor is blind to the mental attitude of the patient to the exact extent that he does not see himself and his own subconscious problems. Therefore I maintain that a doctor must be analysed before he practises analysis. Otherwise the practice of analysis can easily be a great disappointment to him, because he can, under certain circumstances, reach a point where further progress is impossible, a situation which may make him lose his head. He is then readily inclined to assume that psychoanalysis is nonsense, so as to avoid the admission that he has run his vessel ashore. If you are sure of your own psychology you can confidently tell your patient that he does not dream because there is still conscious material to be disposed of. I say that one must be sure of one's self in such cases, for the opinions and unsparing criticisms to which one sometimes has to submit, can be excessively disturbing to one who is unprepared to meet them. The immediate consequence of such a loss of personal balance on the part of the doctor is that he begins to argue with his patient, in order to maintain his influence over him; and this, of course, renders all further analysis impossible.
