These are Heaven and Hell . The belief that humans have both a body and a soul. The soul is believed to be indestructible and survives death. In Christianity Jesus is believed to have come back from the dead at his resurrection. The 'evidence' of ghosts or spirits which may haunt various places and are believed to be the souls of those whose passage into the next life has been disrupted.
Poltergeists are one type of spirit who are believed to throw things around rooms or make noises.
Those claiming to have had a NDE often report the sensation of floating away from their body towards a bright light where they meet a religious figure or holy being. This is often believed to be the moment when a person is going to enter heaven. Some people reason that there has to be an afterlife if evil and suffering is to be dealt with properly. So for Kant there needed to be an afterlife if the world was to make moral sense. They cannot all be true.
