I don't really see any evidence that there is any soul that survives after death, so I think once you die your consciousness just blinks out of existence. You don't know you're dead because there is no more you to know anything, or care about the fact that you're dead. I hope I'm wrong and we go to some great place where I can hang out and be blissful all the time, but I just don't see that as very likely. And if the Christians are right, I'm going to hell anyways, so see y'all there if it exists!
