I'm reading "The Head Trip" by Jeff Warren, an Australian. He mentions that it's Stephen LaBerge's opinion that OBEs are not paranormal and that they're just another variant of lucid dream. How do we know that OBE is paranormal and not just a lucid dream?

I was into OBE for a long time and considered deeply the possibility that it's paranormal and different from LD, but now I'm not sure I'm convinced. The adage "you can't prove it's not paranormal" doesn't satisfy. I don't know if Dr. Sam Parnia has gotten any good results yet.

This doesn't mean LD isn't fun or useful, but it kind of takes away some of my hope in an afterlife.
