ABSTRACT
This chapter suggests that the concept of drug craving, especially in its relation to the concept of hallucinatory satisfaction in dream, closely recalls S. Freud's first "model of desire" with its "hydraulic" metaphor, the "constancy principle" and the concept of "abreaction". The implications arising from the study of drug dreams with a view to Freud's theory of dreams cover different areas, such as the concepts of drive and desire, the role of desire in triggering dreams and the issue of the empirical testability of Freud's dream model. When describing drug dreams, some authors make explicit reference to the Freudian concept of infantile dreams of adults. As in "infantile" dreams of adults, in drug dreams the fulfilment of drug craving is often direct. H. Shevrin, too, pointed at the fact that the description of the neural system that mediates drug craving, that is, the "wanting" or "seeking" system bears much in common with the psychoanalytic concept of drive.
