Anyone interested in paranormal or OBE experience should read up on the career of Susan Blackmoore.
She is an English scientist who at a young age experienced a convincing OBE.
She then decided to spend her career trying to find evidence to prove various paranormal experiences. In the 80s she was somewhat famous in the field.

Eventually, as a GOOD scientist and a person with a flexible, humble mind.
She finally gave up on looking for evidence. Because after a career of searching, after a long futile fight coming up again and again with the same fuzzy logic, charlatans, and deluded people. She couldn't find any evidence to support thier claims.

If find her story fascinating, because she was coming from the perspective of a BELIVER, not a skeptic. She wanted to prove these things. BUT because she was a good scientist, one who accepted the evidence, eventually she became very skeptical.

here's a short article by her explaining herself: http://www.susanblackmore.co.uk/journalism/NS2000.html

I recommend reading other material on her site (there is some on lucid dreaming) she's a very intelligent genuine woman. A scientist in the true sense of the word.
