Sigmund Freud,
Dream Psychology — Chapter 2. The Dream Mechanism
(1920)
“ If we keep closely to the definition that dream work denotes the transference of dream thoughts to dream content, we are compelled to say that the dream work is not creative; it develops no fancies of its own, it judges nothing, decides nothing. It does nothing but prepare the matter for condensation and displacement, and refashions it for dramatization, to which must be added the inconstant last-named mechanism—that of explanatory elaboration. It is true that a good deal is found in the dream content which might be understood as the result of another and more intellectual performance ”
