whether or not he really shows her anything._[EM] I must mention still another series of associations which often serves the purpose of concealing sexual meaning both in dreams and in the neurosis,—I refer to the change of residence series. To change one’s residence is readily replaced by “to remove,” an ambiguous expression which may have reference to clothing. If the dream also contains a “lift” (elevator), one may think of the verb “to lift,” hence of lifting up the clothing. I have naturally an abundance of such material, but a report of it would carry us too far into the discussion of neurotic conditions. Everything leads to the same conclusion, that no special symbolising activity of the mind in the formation of dreams need be assumed; that, on the contrary, the dream makes use of such symbolisations as are to be found ready-made in unconscious thought, because these better satisfy the requirements of dream formation, on account of their dramatic fitness, and particularly on account of their exemption from the censor. (_e_) _Examples—Arithmetic Speeches in the Dream_ Before I proceed to assign to its proper place the fourth of the factors which control the formation of the dream, I shall cite several examples from my collection of dreams for the purpose partly of illustrating the co-operation of the three factors with which we are acquainted, and partly of supplying proof for assertions which have been made without demonstration or of drawing irrefutable inferences from them. For it has been very difficult for me in the foregoing account of the dream activity to demonstrate my conclusions by means of examples. Examples for the individual thesis are convincing only when considered in connection with a dream interpretation; when they are torn from their context they lose their significance, and, furthermore, a dream interpretation, though not at all profound, soon becomes so extensive that it obscures the thread of the discussion which it is intended to illustrate. This technical motive may excuse me for now mixing together all sorts of things which have nothing in common but their relation to the text of the foregoing chapter.
