In the sleep during a lovely dream would be great - but, just think of all the pains a person has had in their life, all the injuries and perhaps things like giving birth - is that last moment more painful, or less? Hopefully of course, painlessly would be the way we all go.

I can't say what comes after (or before life), but the energy has to move and transform, so that makes sense to me. What it transforms into though, doesn't have to be salient life - it could literally be anything.

Live and let live...

Or, die and let live ;D
