I have actually done that before. I was in a rehab that was based on scientology. I had to stare into another individuals eyes/face for two hours. You cannot move or anything. The practice is supposed to teach you complete control over yourself. It allows you to feel comfortable in all situations...blah blah....anyways, that is exactly what happens when you do this. Peoples faces start to morph and change in peculiar ways, like your eyes playing tricks on you. I am not sure what does it or how it happens, but yes, I have experienced the same thing.

Side note: I am not a scientologist nor do I support that church.

Reminds me of those books where you would see the picture if you stared long enough at a page that was covered in some pattern. I forget what they were called. Mind's Eye 3D magic or something.

actually it is kind of like that. you look at a person long enough in the manner of that certain practice they start looking like people you know. Its very strage. I saw faces morph into friends, and I saw peoples faces morph into animals.

This is called transfiguration. I once met a man who claimed to be a Rosicrucian (I think he participated through the mail) who told me about this. You can do it with your own reflection, in a mirror. It's suggested you use two candles for light. He told me that what you are seeing are past incarnations of your soul. All I don't know if that's true, but I do know that if you try it, you WILL see SOMETHING. It really only takes a few minutes for the image to change.
