Although the dream is a narcissistic phenomenon, entirely intrapsychic, it has various communicative functions. This communication occurs within the dream itself with introjected objects, as well as indirectly with the external world. In the waking state the ego is split by the intrusion of demands of reality. In sleep it is reintegrated, resuming a state of advanced (secondary) narcissism. In this state, however, it retains contact with the 'good introjected' (as contrasted with the 'bad expelled') element of the day residue. In various ways the dream reveals a desire to communicate with the analyst. The impulse to communicate is shown by the approach of objects in dreams; the need to break off communication is shown by their withdrawal. Exhibitionistic situations and examinations have similar meanings.
