The shaping of such compound formations must be of great importance to the dream-work, for we can prove, (by the choice of a verbal expression for a thought, for instance) that the common elements mentioned above are purposely manufactured where they originally do not exist. We have already become acquainted with such condensation and compound formations; they played an important part in the origin of certain cases of slips of the tongue. You recall the young man who wished to _inscort_ a woman. Furthermore, there are jokes whose technique may be traced to such a condensation. But entirely aside from this, one may maintain that this appearance of something quite unknown in the dream finds its counterpart in many of the creations of our imagination which fuse together component parts that do not belong together in experience, as for example the centaurs, and the fabulous animals of old mythology or of Boecklin's pictures. For creative imagination can invent nothing new whatsoever, it can only put together certain details normally alien to one another. The peculiar thing, however, about the procedure of the dream-work is the following: The material at the disposal of the dream-work consists of thoughts, thoughts which may be offensive and unacceptable, but which are nevertheless correctly formed and expressed. These thoughts are transformed into something else by the dream-work, and it is remarkable and incomprehensible that this translation, this rendering, as it were, into another script or language, employs the methods of condensation and combination. For a translation usually strives to respect the discriminations expressed in the text, and to differentiate similar things. The dream-work, on the contrary, tries to fuse two different thoughts by looking, just as the joke does, for an ambiguous word which shall act as a connecting link between the two thoughts. One need not attempt to understand this feature of the case at once, but it may become significant for the conception of the dream-work. Although condensation renders the dream opaque, one does not get the impression that it is an effect of dream censorship. One prefers to trace it back to mechanical or economic conditions; but censorship undoubtedly has a share in the process. The results of condensation may be quite extraordinary. With its help, it becomes possible at times to collect quite unrelated latent thought processes into one manifest dream, so that one can arrive at an apparently adequate interpretation, and at the same time conceive a possible further interpretation.
