Perhaps we shall now begin to suspect that dream interpretation is capable of giving us hints about the structure of our psychic apparatus which we have thus far expected in vain from philosophy. We shall not, however, follow this track, but return to our original problem as soon as we have cleared up the subject of dream-disfigurement.
