This article discusses some of the psychoanalytic theory frames (i.e., Freudian, Lacanian, Jungian, Self-psychology, and more recent theories) that explain gender incongruence and its development. The evolution of these theories will be discussed critically, with attention to the diagnosis. A psychoanalyticallytreated case report will be presented and discussed. The analysis of the case, through the originality of the subject and its dreams productions, allows a deeper under standing of the new, unique, and plural interpretation of the gender incongruence phenomenon as a psychological condition in progress.
