Shadow People

It's there (by the clothes stand behind me) when I'm at my desk typing on the computer. It's there again (in the mirror before me) when I'm on my bed doing sit-ups. A shadowy flicker from the corner of my eye that's never in the light, yet never out of sight. What is it? Spooky is what. "Shadow people are supernatural shadow-like creatures of both modern folklore and traditional native American beliefs. According to folklore, they appear as dark forms in the peripheries of people's vision and disintegrate, or move between walls, when noticed". Seen one lately?

P/S: That's precisely why I sleep with the light on.
