A girl dreamt that she saw lying dead before her the only surviving child of her sister amid the same surroundings as a few years before she saw the first child lying dead. She was not sensible of any pain, but naturally combatted the view that the scene represented a desire of hers. Nor was that view necessary. Years ago it was at the funeral of the child that she had last seen and spoken to the man she loved. Were the second child to die, she would be sure to meet this man again in her sister's house. She is longing to meet him, but struggles against this feeling. The day of the dream she had taken a ticket for a lecture, which announced the presence of the man she always loved. The dream is simply a dream of impatience common to those which happen before a journey, theater, or simply anticipated pleasures. The longing is concealed by the shifting of the scene to the occasion when any joyous feeling were out of place, and yet where it did once exist. Note, further, that the emotional behavior in the dream is adapted, not to the displaced, but to the real but suppressed dream ideas. The scene anticipates the long-hoped-for meeting; there is here no call for painful emotions. There has hitherto been no occasion for philosophers to bestir themselves with a psychology of repression. We must be allowed to construct some clear conception as to the origin of dreams as the first steps in this unknown territory. The scheme which we have formulated not only from a study of dreams is, it is true, already somewhat complicated, but we cannot find any simpler one that will suffice. We hold that our psychical apparatus contains two procedures for the construction of thoughts. The second one has the advantage that its products find an open path to consciousness, whilst the activity of the first procedure is unknown to itself, and can only arrive at consciousness through the second one. At the borderland of these two procedures, where the first passes over into the second, a censorship is established which only passes what pleases it, keeping back everything else. That which is rejected by the censorship is, according to our definition, in a state of repression. Under certain conditions, one of which is the sleeping state, the balance of power between the two procedures is so changed that what is repressed can no longer be kept back. In the sleeping state this may possibly occur through the negligence of the censor; what has been hitherto repressed will now succeed in finding its way to consciousness. But as the censorship is never absent, but merely off guard, certain alterations must be conceded so as to placate it. It is a compromise which becomes conscious in this case--a compromise between what one procedure has in view and the demands of the other. _Repression, laxity of the censor, compromise_--this is the foundation for the origin of many another psychological process, just as it is for the dream. In such compromises
