What if I'm already dead and heaven exists but my idea of paradise is to remain in the real world so I never even knew I had died?

Heaven supposedly is meant to be your version of paradise (ish, I have not researched this) and I rather enjoy being a breather. So, what if when I died (if I did) I never realised and ended up in a real world like state heaven. Obviously still with shitty things happening to me otherwise I would catch on... right?
