Research clearly demonstrates that many teenagers have interests in paranormal phenomena (both theoretically, and in terms of experiences and practices), something becoming a commonness. The main self-reported motives of teenagers reflect both curiosity and boredom (Mischo, 1991), but can also implies deeper issues including facing death. Spiritist and occult practices can be a modality of exploration of the limits of the symbolic and of the effects of the signifier (Le Maléfan, 2008). This production of death can also appear, paradoxically, as one form of the fantasies of immortality described by Ph. Gutton (1993) in the juvenile time. This fantasy can develop to become a temporary solution to elaborate a bereavement or a trauma. We would try to show, through clinical cases, how the adolescence, thought as a logical time close to borderline states, can subjectivate death, this « absolute master », by « psychic experiences », i.e. related to practices cultivated for more a century by psychic sciences and spiritualism.
