I'm sure that, as usual, there is not one shred of evidence to support any part of this fairy story.  You see . . . this is how the stories about leprechauns got started.

"First of all if you could reason with religious people, there would be no religious people"

Excellent observation! I live in the Deep South, and although I wouldn't live anywhere else, ignorant religious people abound. They have never questioned their faith--it would never dawn on them to do so. So very close-minded. These people still believe that Noah and the Ark actually happened. And when you ask them: do you really think there were 10,000 species of insects on that boat? You get stunned looks, and then they shut down. Don't want to hear it.

I don't know if this would be in the realm of shadow people, but I have only heard one other reference to it. When we lived in south Texas years ago, my daughter and I would occasionally see a small black triangle-shape whirling across the floor of her bedroom. We could tell they were not solid and sometimes the shapes were slightly distorted--not true triangles. I have never seen these things anywhere else and I have lived in some very active houses. Does anyone know anything about this?
