I'd say nothing happens after death, but I'm skeptical after a few "spiritual" experiences that I've had over the past few months. The heaven/hell theory doesn't seem right to me at all. All there really is in the universe is oneness...and I strongly believe that being in complete oneness comes after death. Of course it is possible to achieve oneness in the mortal life, but only in deep, subconscious, states of spirit. Meditation, rituals, and flowing with the Chakras are only a few ways to achieve oneness for example.
