In this work, the relation between the consciousness and the unconsciousness was studied in patients presenting a neurosurgical coma state. The study includes 29 patients with clinical observations during their hospitalisation period and a follow up for one year after the emergence from the state of coma. The psychoanalytic methods were used, taking in consideration the emotional and personal history of each patient. We attempted to demonstrate the persistence of the unconscious psychic life during coma and the early period after awakening from the coma. In addition, we felt the existence of a sort of direct confrontation with the unconscious psychic life in some patients emerging from a comatose state. The question is also what are the effects of such experience and how would they affect the life of the patients in the future?
