The description of the striking phenomenon of the "ghost sickness"—a massive hysterical conversion often occurring as an element in a mourning process—is given in thorough detail. Conceptualization of the phenomenon follows the theoretical framework of the separation-individuation process as described in the previous article, particularly the aspects of superego formation emphasized there. The authors contend that ghost sickness occurs when a mourning process takes place in individuals who were unable to integrate the aggressive and idealized images of the parental introjects. At the time of mourning the aggressive elements are projected and perceived as a threatening, ominous ghost image that is trying to pull the victim toward death. Reunion wishes and oral-incorporative fears are implied in this condition as well.
