Now that you mention it, I would swear that I have "Seen" dark shapes from time to time, almost like a shadow rapidly running across my vision. I MOST of the time attribute it to "Spots" before my eyes, but sometimes I have had the feeling the it was something evil moving about.

Imagination or fact. I don't really know for sure, only a feeling.
