new assumption. I have in mind cases where one shows astonishment, anger, or resistance in a dream, and that, too, against a party of the dream content itself. Most of these exercises of the critical faculty in dreams are not directed against the dream content, but prove to be portions of dream material which have been taken over and suitably made use of, as I have shown by fitting examples. Some things of this sort, however, cannot be disposed of in such a way; their correlative cannot be found in the dream material. What, for instance, is meant by the criticism not infrequent in dreams: "Well, it's only a dream"? This is a genuine criticism of the dream such as I might make if I were awake. Not at all infrequently it is the forerunner to waking; still oftener it is preceded by a painful feeling, which subsides when the certainty of the dream state has been established. The thought: "But it's only a dream," occurring during the dream, has the same object which is meant to be conveyed on the stage through the mouth of the beautiful Helen von Offenbach; it wants to minimise what has just occurred and secure indulgence for what is to follow. Its purpose is to reassure and, so to speak, put to sleep a certain instance which at the given moment has every reason to be active and to forbid the continuation of the dream—or the scene. It is pleasanter to go on sleeping and to tolerate the dream, "because it's only a dream anyway." I imagine that the disparaging criticism, "But it's only a dream," enters into the dream at the moment when the censor, which has never been quite asleep, feels that it has been surprised by the already admitted dream. It is too late to suppress the dream, and the instance therefore carries with it that note of fear or of painful feeling which presents itself in the dream. It is an expression of the esprit d'escalier on the part of the psychic censor.
In this example we have faultless proof that not everything which the dream contains comes from the dream thoughts, but that a psychic function which cannot be differentiated from our waking thoughts may make contributions to the dream content. The question now is, does this occur only in altogether exceptional cases, or does the psychic instance which is usually active only as censor take a regular part in the formation of dreams?
