Regarding the question of consciousness "continuation" responding to a question about "heaven" some of the Bardo teachings are suggestive, leading to: If consciousness continues and is freed of perceptual sense anchors, then it would be whatever you imagine or wish. Dream Yoga and Pure Land meditations are attempts at preparation for this possibility, I think. It might follow that, if your wishes overlapped with those of others they might co-exist with your imaginings.
