It is the process of displacement which is chiefly responsible for our being unable to discover or recognize the dream-thoughts in the dream-content, unless we understand the reason for their distortion. Nevertheless, the dream-thoughts are also submitted to another and milder sort of transformation, which leads to our discovering a new achievement on the part of the dream-work - one, however, which is easily intelligible. The dream-thoughts which we first come across as we proceed with our analysis often strike us by the unusual form in which they are expressed; they are not clothed in the prosaic language usually employed by our thoughts, but are on the contrary represented symbolically by means of similes and metaphors, in images resembling those of poetic speech. There is no difficulty in accounting for the constraint imposed upon the form in which the dream-thoughts are expressed. The manifest content of dreams consists for the most part in pictorial situations; and the dream-thoughts must accordingly be submitted in the first place to a treatment which will make them suitable for a representation of this kind. If we imagine ourselves faced by the problem of representing the arguments in a political leading article or the speeches of counsel before a court of law in a series of pictures, we shall easily understand the modifications which must necessarily be carried out by the dream-work owing to considerations of representability in the content of the dream.

The psychical material of the dream-thoughts habitually includes recollections of impressive experiences - not infrequently dating back to early childhood - which are thus themselves perceived as a rule as situations having a visual subject matter. Wherever the possibility arises, this portion of the dream-thoughts exercises a determining influence upon the form taken by the content of the dream; it constitutes, as it were, a nucleus of crystallization, attracting the material of the dream-thoughts to itself and thus affecting their distribution. The situation in a dream is often nothing other than a modified repetition, complicated by interpolations, of an impressive experience of this kind; on the other hand, faithful and straightforward reproductions of real scenes only rarely appear in dreams.
