I believe in the afterlife. Well, not so much believing as it is hoping for, though. I guess my real belief in what happens after death is, well, you just stop everything. Breathing, seeing, feeling, thinking, dreaming. You're done and gone, forever. Seems like a depressing thought which is why I hope for afterlife or even reincarnation.
Also, Iban, seeing as you appear to have a scientific explanation for most everything, I'm curious as to what your explanation for ghosts might be. I mean, you can't just disregard the millions of videos and claims made by all kinds of people. Sure some are fake, but they can't all be, so what do you think?
