When I was a kid, Santa, the Tooth Fairy, my stuffed animals - they were real. There is the tremendous suspension of disbelief that you have as a child. It's harder as an adult.
I was raised in a deeply Catholic family. There was a sense that everything we were doing was to prepare ourselves for an afterlife in heaven. In my teenage years, that became less important to me. Eventually, that turned into agnosticism, which became atheism.
I've never had an actual haunting experience, in the way you might anticipate a ghost in a movie haunting someone, but I do feel presences around me all the time, and I do feel that memories haunt us the way ghosts haunt us or might haunt characters in a film.
