We can go no further here, for you have probably long been disturbed by a reflection which deserves to be heard. Are the day-remnants, you ask, really unconscious in the same sense as the unconscious wish which is essential to making them suitable for the dream? You discern correctly. Here lies the salient point of the whole affair. They are not unconscious in the same sense. The dream wish belongs to a different unconsciousness, that which we have recognized as of infantile origin, fitted out with special mechanisms. It is entirely appropriate to separate these two types of unconsciousness and give them different designations. But let us rather wait until we have become acquainted with the field of neurotic symptoms. If people say one unconsciousness is fantastic, what will they say when we acknowledge that we arrived at our conclusions by using two kinds of unconsciousness? Let us stop here. Once more you have heard something incomplete; but is there not hope in the thought that this science has a continuation which will be brought to light either by ourselves or by those to follow? And have not we ourselves discovered a sufficient number of new and surprising things? FIFTEENTH LECTURE THE DREAM _Doubtful Points and Criticism_ Let us not leave the subject of dreams before we have touched upon the most common doubts and uncertainties which have arisen in connection with the new ideas and conceptions we have discussed up to this point. The more attentive members of the audience probably have already accumulated some material bearing upon this.
