Well, I have to disagree with you Dan. (Like this is news, eh? ) I went to the website, and I agree that the voices were unmistakable, until I started clicking on them blindly. Then, when not preconditioned as to exactly what to hear, I heard completely different phrases than the site reported. As an example, the one labeled "I was seeing the war" (which the website also says has been heard as "I was seeing the water" or "I will see you no more" sounded to me like "You've never been, we are". Other samples that I clicked blindly gave similarly different results.
On a related note, I find it somewhat interesting that this group who runs this website began at the same time that the movie Poltergiest was released, along with it's scene of the little girl communicating with spirits through the televisions white noise...
