I Have A Theory About What Happens After Death
I believe that anything you expect to happen can happen from death until Judgement Day. Upon that day, all souls will be retrieved from their dwelling spots or current bodies and sentenced to either Heaven or Hell. Reincarnation, haunting, and other scenarios (which I'm unable to imagine right now) are possible. And those in a heaven, hell, or other fantasized locations will not know them to be illusions until that day.
