I have very good reasons to believe the mind continues after the body dies. Perhaps we'll get into that, if you're interested, in this string, but I'm more interested in speculating about what the afterlife would have to be like, if there is such a thing.
Is it like a dream?
Is it simply non-existence--no mind, no realization of any sort?
Is it a world, a universe of its own?
What does Morpheus say to Neo in The Matrix? "Have you ever had a dream that seemed so real? What if you never woke up? How would you know it was a dream?" ...or something to that effect.
