II THE DREAM MECHANISM

The need of discovering some motive for this bewildering work of the dream is even more called for in the case of displacement than in condensation.

Although the work of displacement must be held mainly responsible if the dream thoughts are not refound or recognized in the dream content (unless the motive of the changes be guessed), it is another and milder kind of transformation which will be considered with the dream thoughts which leads to the discovery of a new but readily understood act of the dream work. The first dream thoughts which are unravelled by analysis frequently strike one by their unusual wording. They do not appear to be expressed in the sober form which our thinking prefers; rather are they expressed symbolically by allegories and metaphors like the figurative language of the poets. It is not difficult to find the motives for this degree of constraint in the expression of dream ideas. The dream content consists chiefly of visual scenes; hence the dream ideas must, in the first place, be prepared to make use of these forms of presentation. Conceive that a political leader's or a barrister's address had to be transposed into pantomime, and it will be easy to understand the transformations to which the dream work is constrained by regard for this _dramatization of the dream content_.

Around the psychical stuff of dream thoughts there are ever found reminiscences of impressions, not infrequently of early childhood--scenes which, as a rule, have been visually grasped. Whenever possible, this portion of the dream ideas exercises a definite influence upon the modelling of the dream content; it works like a center of crystallization, by attracting and rearranging the stuff of the dream thoughts. The scene of the dream is not infrequently nothing but a modified repetition, complicated by interpolations of events that have left such an impression; the dream but very seldom reproduces accurate and unmixed reproductions of real scenes.

The dream content does not, however, consist exclusively of scenes, but it also includes scattered fragments of visual images, conversations, and even bits of unchanged thoughts. It will be perhaps to the point if we instance in the briefest way the means of dramatization which are at the disposal of the dream work for the repetition of the dream thoughts in the peculiar language of the dream.

The dream thoughts which we learn from the analysis exhibit themselves as a psychical complex of the most complicated superstructure. Their parts stand in the most diverse relationship to each other; they form backgrounds and foregrounds, stipulations, digressions, illustrations, demonstrations, and protestations. It may be said to be almost the rule that one train of thought is followed by its contradictory. No feature known to our reason whilst awake is absent. If a dream is to grow out of all this, the psychical matter is submitted to a pressure which condenses it extremely, to an inner shrinking and displacement, creating at the same time fresh surfaces, to a selective interweaving among the constituents best adapted for the construction of these scenes. Having regard to the origin of this stuff, the term _regression_ can be fairly applied to this process. The logical chains which hitherto held the psychical stuff together become lost in this transformation to the dream content. The dream work takes on, as it were, only the essential content of the dream thoughts for elaboration. It is left to analysis to restore the connection which the dream work has destroyed.

The dream's means of expression must therefore be regarded as meager in comparison with those of our imagination, though the dream does not renounce all claims to the restitution of logical relation to the dream thoughts. It rather succeeds with tolerable frequency in replacing these by formal characters of its own.
