PROVE to me that man did not lie about his experiment. Prove to me he did not know the pattern his subjects eyes allways move in sleep and fake his results. PROVE to me that lucid dreams exist? It can not be done. PROVE to me that because near death, sufficated people see visions like OBE that they did not in fact have them or that the one thing (thier visions) disprove the possibilty of another. I think people who want to yell OBE does not exist honestly just want the world to fit thier own relious beliefs.
