logical relations in question with approximate correctness, or, as is easily possible in such a difficult matter, in an erroneous and fragmentary manner. Whatever changes may be made in the interpretation of the psychic censor and of the correct and of the abnormal elaboration of the dream content, the fact nevertheless remains that such processes are active in dream formation, and that essentially they show the closest analogy to the processes observed in the formation of the hysterical symptoms. The dream is not a pathological phenomenon, and it does not leave behind an enfeeblement of the mental faculties. The objection that no deduction can be drawn regarding the dreams of healthy persons from my own dreams and from those of neurotic patients may be rejected without comment. Hence, when we draw conclusions from the phenomena as to their motive forces, we recognise that the psychic mechanism made use of by the neuroses is not created by a morbid disturbance of the psychic life, but is found ready in the normal structure of the psychic apparatus. The two psychic systems, the censor crossing between them, the inhibition and the covering of the one activity by the other, the relations of both to consciousness—or whatever may offer a more correct interpretation of the actual conditions in their stead—all these belong to the normal structure of our psychic instrument, and the dream points out for us one of the roads leading to a knowledge of this structure. If, in addition to our knowledge, we wish to be contented with a minimum perfectly established, we shall say that the dream gives us proof that the suppressed material continues to exist even in the normal person and remains capable of psychic activity. The dream itself is one of the manifestations of this suppressed material; theoretically, this is true in all cases; according to substantial experience it is true in at least a great number of such as most conspicuously display the prominent characteristics of dream life. The suppressed psychic material, which in the waking state has been prevented from expression and cut off from internal perception by the antagonistic adjustment of the contradictions, finds ways and means of obtruding itself on consciousness during the night under the domination of the compromise formations.
