ABSTRACT
Unconscious Phantasy, the central object of the psychoanalytic activity, is one of the most important theoretical and clinical concepts of Psychoanalysis. Unconscious phantasy is at the core of what Freud defines as "psychic reality". This chapter considers three dimensions of the Unconscious Phantasy. The first level refers to the structural dimension of the Unconscious. The second dimension of the Unconscious that Freud described belongs to the Dynamic Unconscious, that implies the inter-systemic level and the communicative aspect that unconscious phantasies possess, in their role of connection between internal reality and external reality with all the vicissitudes that take place in it. The third dimension is the relationship that the Unconscious phantasy has with the experiences of pleasure and pain, physical and mental pain, not only by expressing them but in the way that pleasure and pain determine the way that mental organization is shaped by them.
