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.
1. You may have received the impression that the results of our work of interpretation of the dream have left so much that is uncertain, despite our close adherence to technique, that a true translation of the manifest dream into the latent dream thoughts is thereby rendered impossible. In support of this you will point out that in the first place, one never knows whether a specific element of the dream is to be taken literally or symbolically, since those elements which are used symbolically do not, because of that fact, cease to be themselves. But if one has no objective standard by which to decide this, the interpretation is, as to this point, left to the discretion of the dream interpreter.
