If the two childhood scenes of urinating are otherwise closely connected with the desire for greatness, their rehabilitation on the trip to the Aussee was further favoured by the accidental circumstance that my compartment had no water-closet, and that I had to expect embarrassment on the ride as actually happened in the morning. I awoke with the sensation of a bodily need. I suppose one might be inclined to credit these sensations with being the actual stimulus of the dream; I should, however, prefer a different conception—namely, that it was the dream thoughts which gave rise to the desire to urinate. It is quite unusual for me to be disturbed in sleep by any need, at least at the time of this awakening, a quarter of four in the morning. I may forestall further objection by remarking that I have hardly ever felt a desire to urinate after awakening early on other journeys made under more comfortable circumstances. Moreover, I can leave this point undecided without hurting my argument. Since I have learned, further, from experience in dream analysis that there always remain important trains of thought proceeding from dreams whose interpretation at first seems complete (because the sources of the dream and the actuation of the wish are easily demonstrable), trains of thought reaching back into earliest childhood, I have been forced to ask myself whether this feature does not constitute an essential condition of dreaming. If I were to generalise this thesis, a connection with what has been recently experienced would form a part of the manifest content of every dream and a connection with what has been most remotely experienced, of its latent content; and I can actually show in the analysis of hysteria that in a true sense these remote experiences have remained recent up to the present time. But this conjecture seems still very difficult to prove; I shall probably have to return to the part played by the earliest childhood experiences, in another connection (Chapter VII.). Of the three peculiarities of dream memory considered at the beginning, one—the preference for the unimportant in the dream content—has been satisfactorily explained by tracing it back to dream disfigurement. We have been able to establish the existence of the other two—the selection of recent and of infantile material—but we have found it impossible to explain them by the motive of dream. Let us keep in mind these two characteristics, which still remain to be explained or evaluated; a place for them will have to be found elsewhere, either in the psychology of the sleeping state, or in the discussion of the structure of the psychic apparatus which we shall undertake later, after we have learned that the inner nature of the apparatus may be observed through dream interpretation as though through a window.
