David Lynch. The very idea is terrifying. The only hinting of something like this besides his involvement with Transcendental Meditation (which, in his and many other stars cases, seems to be a very genuine belief; I don't think he is trying to profit off of people) is that one time Michael J. Anderson ("The Man From Another Place") made a bunch of really out there accusations on Facebook, but this happened seemingly after a financial dispute about his payment on Twin Peaks: Season 3, and several people he mentioned did not corroborate what he said whatsoever.
Just about everyone else? I've lost hope in humanity. I can take it. But, please. Not David Lynch...
