The work of mourning and organization of the mental space may be seriously disturbed by the real loss of the object and the way how communication with the “still alive” objects is built. Certain obstacles in communication with significant people make the mental separation difficult. The problem of separation, individuation and building of somebody’s own mental space is linked to the way in which the child mourns in relation to the central objects of early childhood. Especially the real loss of a parental object during the early childhood implies a traumatic moment which will excessively dramatize the oedipal issues. In this context, the analysis of the infantile material and development of an analytical work, which would perlaborate the trauma of the loss under a full oedipal conflict of one of the parents, as well as the subjectivation difficulties deriving from this trauma are the indispensable elements of a psychoanalytic work.
