I think we also have an easy task in recognising the psychic force which makes itself felt in the circumstances of dream displacement. The result of this displacement is that the dream content no longer resembles the core of the dream thoughts at all, and that the dream reproduces only a disfigured form of the dream-wish in the unconscious. But we are already acquainted with dream disfigurement; we have traced it back to the censorship which one psychic instance in the psychic life exercises upon the other. Dream displacement is one of the chief means for achieving this disfigurement. _Is fecit, cui profuit._ We may assume that dream displacement is brought about by the influence of this censor, of the endopsychic repulsion.[DS] The manner in which the factors of displacement, condensation, and over-determination play into one another in the formation of the dream, which is the ruling factor and which the subordinate one, all this will be reserved as the subject of later investigations. For the present we may state, as a second condition which the elements must satisfy in order to get into the dream, that _they must be withdrawn from the censor of resistance_. From now on we shall take account of dream displacement as an unquestionable fact in the interpretation of dreams. (_c_) _Means of Representation in the Dream_ Besides the two factors of dream condensation and dream displacement which we have found to be active in the transformation of the latent dream material into the manifest content, we shall come in the course of this investigation upon two other conditions which exercise an unquestionable influence upon the selection of the material which gets into the dream. Even at the risk of seeming to stop our progress, I should like to glance at the processes by which the interpretation of dreams is accomplished. I do not deny that I should succeed best in making them clear, and in showing that they are sufficiently reliable to insure them against attack, by taking a single dream as a paradigm and developing its interpretation, as I have done in Chapter II. in the dream of “Irma’s Injection,” and then putting together the dream thoughts which I have discovered, and reconstructing the formation of the dream from them—that is to say, by supplementing the analysis of dreams by a synthesis of them. I have accomplished this with several specimens for my own instruction; but I cannot undertake to do it here because I am prevented by considerations, which every right-minded person must approve of, relative to the psychic material necessary for such a demonstration. In the analysis of dreams these considerations present less difficulty, for an analysis may be incomplete and still retain its value even if it leads only a short way into the thought labyrinth of the dream. I do not see how a synthesis could be anything short of complete in order to be convincing. I could give a complete
