286 the thoughts which analysis brings to light, many can be found which are far removed from the central idea of the dream, and which appear distinguished from the rest as artificial interpolations for a definite purpose. Their purpose may easily be discovered; they are just the ones which establish a connection, often a forced and far-fetched one, between the dream content and the dream thoughts, and if these elements were to be weeded out, not only over-determination but also a sufficient determination by means of the dream thoughts would often be lacking for the dream content. We are thus led to the conclusion that manifold determination, which decides the selection made by the dream, is perhaps not always a primary factor in dream formation, but is often the secondary manifestation of a psychic power which is still unknown to us. But in spite of all this, manifold determination must nevertheless control the entrance of individual elements into the dream, for it is possible to observe that it is established with considerable effort in cases where it does not result from the dream material without assistance.

The assumption is not now far distant that a psychic force is expressed in dream activity which on the one hand strips elements of high psychic value of their intensity, and which on the other hand creates new values, by way of over-determination, from elements of small value, these new values subsequently getting into the dream content. If this is the method of procedure, there has taken place in the formation of the dream a transference and displacement of the psychic intensities of the individual elements, of which the textual difference between the dream and the thought content appears as a result. The process which we assume here is nothing less than the essential part of the dream activity; it merits the designation of ''dream displacement. Dream displacement and dream condensation'' are the two craftsmen to whom we may chiefly attribute the moulding of the dream.

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
