An interesting thing about death, evidenced by most of the previous posts, is the constant use of metaphors to describe what happens afterwards. The interesting thing about these metaphors is that, unlike other metaphors, with a ground and an argument -- so that you know why they are metaphors, this area of metaphor is different: we do not know whether the metaphors we use to describe what, if anything, happens after death, are really metaphors.
I don't think that these are metaphors but rather euphemisms. The purpose of the euphemism in this case is to obscure and dull the fact of our inevitable mortality
