I have very strange dreams too, often quite intense and highly detailed. But most people tell me they either don't dream, or their dreams are quite mundane. Sort of beside the point. People lie for dumb reasons all the time. I tend to lump in holy experiences with the like of alien abductions and bigfoot sightings, and I think people tend to exaggerate when they have experiences like that. A classic example is when a friend of mine claimed to have seen orbs floating in the woods... when another friend told his account of what happened it was guys on the other side of the forest with flashlights. People are full of shit. No reason to think NDEs are immune to this human nature.
If you're frightened of dying, and you're holding on, you'll see devils tearing your life away. But if you've made your peace, then the devils are really angels, freeing you from the Earth.
