You know when you die, Christians (and other religions) say that depending on whether you've been good or bad you'll go to Heaven or Hell... What if that's a lucid dream? I know when you die your brain stops... But if you think... You are the only conscious one to you, so maybe life is a kind of lucid dream?
OBE (out of body experiences) are kind of like when people say your spirit leaves your body and you go to heaven/hell, right? What if you believe you've been good and whatever you imagined Heaven to be like, it would be, and if you believed you've been bad, you think you'll get punished and so would go to, perhaps, a nightmare about hell...

Am I getting through to anyone 0.o;
