Why are they fantasies? There have been enough near death experiences recorded to give the concept some credence and I don't care if you believe or not, you can't convince those who have had them that they are fantasies. Now, a belief in eternal torture or even eternal heaven I can see being detrimental to the psyche because it takes away from living life in the present, which is tantamount to not living at all. (Like the others, my attention span is too short to watch the whole thing).
