The thought of being conscious after death - no body, no ability to do anything besides think and be aware - is terrifying. Our thoughts only exist because we are constantly encountering and learning about new things. If you take that away and give us some massless bodiless orb to exist in - we would quickly run out of trains of thought and be forever bored. It might take a bit and we might reach some pretty amazing conclusions as we take the time to really follow each train of thought to completion. But forever is a long time and we'd most likely end up incredibly bored after a while. Sounds like hell to me.

I hope we just cease to exist. I think it's best that way. Perhaps we go off into some other dimension and "level up" so to speak. New rules of existence, new interactions and experiences to learn, etc. If we did carry our memories and consciousness with us it would be interesting to see if there were groups or factions of new people who have made "the old days" a religion or something.

I don't know though. I'm not going to let the unknown dictate how I live my life today and I'm going to make the best of the situation I'm in right now.
