The Ganzfield Procedure? First of all, why would I tape ping-pong ball halves to my face? Couldn't I just close my eyes for the same effect? As for the radio tuned to static... that's just white noise, like a fan or something. I sometimes turn on a source of white noise like that to help me sleep. The "Ganzfield Procedure" doesn't make you hallucinate; it just puts you to sleep, and then you dream!
Oh, PETA, what will you do next? I'm an animal lover myself, and I think PETA's heart is in the right place (for the most part), but their methods stink.
