necrophobia

n. fear of the dead; fear of death

Necrophobia or thanatophobia is the fear of death or dead things (e.g., corpses) as well as things associated with death (e.g., coffins). Necrophobia is derived from Greek nekros for "corpse" and -phob- for "fear". Thanatophobia is derived from Thanatos (θάνατος: "death"), the personification of death. The usage differs, although in common speech the terms are used interchangeably. Thanatophobia is more specifically, but not limited to the fear of one's own death or dying.
