A General Introduction to Psychoanalysis by Sigmund Freud

Archaic Remnants and Infantilism in the Dream

LET us revert to our conclusion that the dream-work, under the influence of the dream censorship, transforms the latent dream thoughts into some other form of expression. The latent thoughts are no other than the conscious thoughts known to us in our waking hours; the new mode of expression is incomprehensible to us because of its many-sided features. We have said it extends back to conditions of our intellectual development which we have long progressed beyond, to the language of pictures, the symbol-representations, perhaps to those conditions which were in force before the development of our language of thought. So we called the mode of expression of the dream-work the archaic or regressive.
