The experience of the pubertaire has a central place in the treatment of the adult. It is the trace out of which the dream and the psychical work of the adolescens develop. Affirming and confirming its innovative value in the revisiting of childhood sexuality inspires images in dreams in the wake of adolescent subjectivation. This point of view justifies interventions aimed at deconstructing infantile phallic theories whose rigidity is liable to stifle the pubertaire.
