Facing one’s own death is radically different from being concerned with the death of others. the total disintegration and the end of my world. The fear of my own death comes from the fear of my extinction as a human being. This causes me a great deal of anxiety. I may be able to face other people’s death but may find it virtually impossible to come to terms with my own death. Heidegger says Dasein cannot experience its own death. As long as Dasein exists, it is not complete, that is, there are still some of its possibilities outstanding. If, however, Dasein dies, then it is ‘no-longerthere’.
Death is existentially significant when one perceives one’s existence in the light of Being, not if it is merely taken as an empirical event that will happen someday
