#13: Shadow People

You're sitting in your living room. From the corner of of your eye you see what looks like a shadowy figure crossing your hallway. Or in the middle of the night you wake up and see a dark figure, perched at the foot of your bed. The figure is wearing a fedora hat and a long, black coat. If you have seen any of these entities, you are not alone. Who or what are these recurring shadowy figures typically known as shadow people?
