300 safely assume that my ego is concealed behind that person by means of identification. I am permitted to supplement my ego. On other occasions when my ego appears in the dream, I am given to understand by the situation in which it is placed that another person is concealing himself behind the ego. In this case the dream is intended to give me notice that in the interpretation I must transfer something which is connected with this person—the hidden common feature—to myself. There are also dreams in which my ego occurs along with other persons which the resolution of the identification again shows to be my ego. By means of this identification I am instructed to unite in my ego certain ideas to whose acceptance the censor has objected. I may also give my ego manifold representation in the dream, now directly, now by means of identification with strangers. An extraordinary amount of thought material may be condensed by means of a few such identifications.

The resolution of the identification of localities designated under their own names is even less difficult than that of persons, because here the disturbing influence of the ego, which is all-powerful in the dream, is lacking. In one of my dreams about Rome (p. 164) the name of the place in which I find myself is Rome; I am surprised, however, at the great number of German placards at a street corner. The latter is a wish-fulfilment, which immediately suggests Prague; the wish itself probably originated at a period in my youth when I was imbued with a German nationalistic spirit which is suppressed to-day. At the time of my dream I was looking forward to meeting a friend in Prague; the identification of Rome and Prague is thus to be explained by means of a desired common feature; I would rather meet my friend in Rome than in Prague, I should like to exchange Prague for Rome for the purpose of this meeting.

The possibility of creating compositions is one of the chief causes of the phantastic character so common in dreams, in that it introduces into the dream elements which could never have been the objects of perception. The psychic process which occurs in the formation of compositions is obviously
