I thought the word "afterlife" was pretty self explanatory: after this life.

I have shared what I believe to be the afterlife in other, more religious threads, so I won\'t go into detail. I will say that right after we die, I believe that our bodies are left in the ground (or whereever the bodies are put), and our spirits leave our bodies. Our spirits stay on this world though until a later time.
I believe that it is
possible for "ghosts" to exist, or in other words, for the spirits of the dead to be visible by people on this side of the vail. But I have not seen one, so I could not say if ghosts are real or not.
