After these remarks concerning the effects of the dream censor, let us now turn to their dynamics. I hope you will not consider the expression too anthropomorphically, and picture the dream censor as a severe little manikin who lives in a little brain chamber and there performs his duties; nor should you attempt to localize him too much, to think of a brain center from which his censoring influence emanates, and which would cease with the injury or extirpation of this center. For the present, the term "dream censor" is no more than a very convenient phrase for a dynamic relationship. This phrase does not prevent us from asking by what tendencies such influence is exerted and upon which tendencies it works; nor will we be surprised to discover that we have already encountered the dream censor before, perhaps without recognizing him. For such was actually the case. You will remember that we had a surprising experience when we began to apply our technique of free association. We then began to feel that some sort of a resistance blocked our efforts to proceed from the dream element to the unconscious element for which the former is the substitute. This resistance, we said, may be of varying strength, enormous at one time, quite negligible at another. In the latter case we need cross only a few intermediate steps in our work of interpretation. But when the resistance is strong, then we must go through a long chain of associations, are taken far afield and must overcome all the difficulties which present themselves as critical objections to the association technique. What we met with in the work of interpretation, we must now bring into the dream work as the dream censor. The resistance to interpretation is nothing but the objectivation of the dream censor. The latter proves to us that the force of the censor has not spent itself in causing the dream distortion, has not since been extinguished, but that this censorship continues as a permanent institution with the purpose of preserving the distortion. Moreover, just as in the interpretation the strength of the resistance varied with each element, so also the distortion produced by the censor in the same dream is of varying magnitude for each element. If one compares the manifest with the latent dream one sees that certain isolated latent elements have been practically eliminated, others more or less modified, and still others left unchanged, indeed, have perhaps been taken over into the dream content with additional strength.
