Material is presented from the ongoing analysis of a patient with validated repeated primal scene exposure from birth until the age of twelve. A recurrent element in the manifest content of certain dreams, whereby the patient sees himself in the dual representations of both observer and observed is related to the original traumatic scenes as well as to the presence of a mirror in the parental bedroom. Following the analysis of these dreams, the patient acquired a firmer sense of conviction

of actually having witnessed the primal scene. The comparison is made between these dreams and the state of depersonalization from which the patient suffered. Special attention is focused on the defensive functions of these phenomena.
