Is death the sort of thing that is ever now?

Please don't move this to the Philosophy stack unless absolutely necessary. My personal belief in an afterlife is based on: 1. Being indefinite about "what is now?" 2. I assume that "my death" is semantically precise in some way, it's clear what we all mean by that 3. Linking these two, in terms of the impossibility of vague identity. Some people might object to my version of time or death, so while I am more interested in understanding 'vague identity', I cannot yet get started rhetorically. What's going on here? Which of these moves are allowed in the language game?
