curiosity thrilled the cat

Basically, when you die your spirit leaves your body, actually at first you can see all your life, like reflected in a magic mirror. Then you start floating like a ghost, you can see anything happening around you, you can hear everything but you can't communicate. Then you see lights, lights of all different colours, these lights are the doors that pull you into other planes of existence, but most people actually like this world so much, that they don't want to be taken away, so the whole thing turns into a bad trip, and the only way out is to get reincarnated.
