We have fully recognized the role which Scherner ascribes to the dream phantasy, and even his interpretation; but we have been obliged, so to speak, to conduct them to another department in the problem.  It is not the dream that produces the phantasy but the unconscious phantasy that takes the greatest part in the formation of the dream thoughts.  We are indebted to Scherner for his clew to the source of the dream thoughts, but almost everything that he ascribes to the dream-work is attributable to the activity of the unconscious, which is at work during the day, and which supplies incitements not only for dreams but for neurotic symptoms as well.  We have had to separate the dream-work from this activity as being something entirely different and far more restricted.  Finally, we have by no means abandoned the relation of the dream to mental disturbances, but, on the contrary, we have given it a more solid foundation on new ground.

Thus held together by the new material of our theory as by a superior unity, we find the most varied and most contradictory conclusions of the authorities fitting into our structure; some of them are differently disposed, only a few of them are entirely rejected.  But our own structure is still unfinished.  For, disregarding the many obscurities which we have necessarily encountered in our advance into the darkness of psychology, we are now apparently embarrassed by a new contradiction.  On the one hand, we have allowed the dream thoughts to proceed from perfectly normal mental operations, while, on the other hand, we have found among the dream thoughts a number of entirely abnormal mental processes which extend likewise to the dream contents.  These, consequently, we have repeated in the interpretation of the dream.  All that we have termed the “dream-work” seems so remote from the psychic processes recognized by us as correct, that the severest judgments of the authors as to the low psychic activity of dreaming seem to us well founded.

Perhaps only through still further advance can enlightenment and improvement be brought about.  I shall pick out one of the constellations leading to the formation of dreams.

We have learned that the dream replaces a number of thoughts derived from daily life which are perfectly formed logically.  We cannot therefore doubt that these thoughts originate from our normal mental life.  All the qualities which we esteem in our mental operations, and which distinguish these as complicated activities of a high order, we find repeated in the dream thoughts.  There is, however, no need of assuming that this mental work is performed during sleep, as this would materially impair the conception of the psychic state of sleep we have hitherto adhered to.  These thoughts may just as well have originated from the day, and, unnoticed by our consciousness from their inception, they may have continued to develop until they stood complete at the onset of sleep.  If we are to conclude
