The author inquires whether dreams related in psychoanalysis can be indicator of curative change, and if so what affective conditions go to making this possible. To answer this question convincingly, he puts forward a new model of dream generation. It proceeds from the relation between cognitive elements, regulatory affective processes and species of interaction represented in individual dream situations. Such a model requires a new theory of mental representation, affective processes and memory. For precise analysis of change processes, Moser has recourse to a coding system for dream content. Finally he compares change processes in dreams with those in the psychoanalytic situation and suggests hypotheses on the extent to which changes in dreams can be indicators of changes in the psychoanalytic process.
