I believe any number of things are possible when our bodies die. Some may go to a heaven, some may go to a hell, some may reincarnate, some may reincarnate after a time elsewhere, some may discorporate and pass on their traits to multiple people, some may become ghosts, some may just wink out of existence. I would tend to think that what one expects, even if only subconsciously, may play a role, along with (for those of us who are religious theists) our relationships to various gods/spirits.
