I've investigated this phenomena for decades now. Part of my personal distrust of government (on the national level) stems from their cover up of this reality.Of course I know about the paralytic sleep theory, which I think is extremely lame. And insulting to the victims of this horrible experience. To me it's the equivalent of telling a rape victim it's all in her head. And funny that you mention that it was only one theory of (probably) many. They can't all be right though. And TeeVee is probably the worst source for information on this topic. Or any other topic, come to think of it...
