Well,
since the soul has weight and exists (not very accurate but somewhat true), we can't be sure of anything that occurs post mortem, for all we know it could just turn into anti-matter causing afterlife to be an ethereal prison of sorts
Personally, I like to think that once dead, it's the end of everything, that nothing exists post-mortem, despite what religion likes to claim. If afterlife really existed, we'd have at least valid hints towards it's existence that aren't only present in religion. To sum up, once you die, nothing happens, black emptiness for all eternity at best, black emptiness for all eternity while you are conscious of it at worst
