The wish-dream of Freud's type has presented itself for consideration here, because it is a special and elaborate illustration of symbolism in dreaming. The important place of symbols in dreaming is by no means dependent on the validity of this particular type of dream, and we may now proceed to continue the discussion of the significance of the symbolic tendency during sleep in its most important form. The symbols we have so far been mainly concerned with have been the result of a tendency of dreaming consciousness to objectify feelings and affections within the organism in concrete objects or processes outside the organism. In its complete form this symbolic tendency becomes the objectivation of part of the dreamer's feelings or personality in a distinct imaginary personality. A process of dramatisation occurs, and the dreamer finds himself in action and reaction, friendly or hostile or indifferent, with seemingly external personalities which, by the light of the analysis possible on awakening, are demonstrably created out of split-off portions of his own personality.[163] A common and simple form of such objectivation, closely allied to some of the symbolisms already brought forward, occurs when the dreamer sees the image of a person suffering from some affection of a part of the body and finds on awakening that he is himself experiencing pain or discomfort in that part. Thus a medical man dreams he is examining a tumour in a patient's groin, and on awakening finds slight irritation in the same region of his own body. And similarly, just as our bodily needs, when experienced during sleep, may be symbolised by inanimate natural objects and processes, so they may also become objective in the image of another person who is occupied in gratifying the need which we are ourselves unconsciously experiencing.
