I'm gonna swipe a bit of a post I made on BHB for this:
I believe that sentient life is an amazing accident, and death is most likely the end of my consciousness.
As for where I would like to 'go after,' in the sense of what I'd like to be done with my remains... I've seen things like blown glass with ashes in it, as memorial objects. That seems like a nice keepsake, if there was someone in my life who'd want that kind of thing, at the point when I die. I kind of like the idea that it could be handed down, to people increasingly distant from any relation to me. Just a pretty object, eventually, its origin forgotten... and then someone would wonder about it, and figure out what it was. Maybe not precisely who it was, but that it contained human remains, as a form of memorial. And they'd be unsettled, and a little sad, because they live in the far future, and humans are effectively immortal by then.
And then they'd go about their life, because that's what you do.
But they'd keep the glass trinket, and they'd sometimes think of me, across a vast gulf of time.
And it is some comfort to me, not to think that my consciousness will survive... but that there will be conscious beings, into the far, far future, who are not unlike myself.
