This troper wrote a story for her creative writing class involving a LivingShadow. It ended up murdering it's "host" at the end.

This troper has seen shadow people several times during childhood. They appeared to be featureless humanoid figures whose limbs ended in points rather than hands or feet, briefly seen running along a wall. In later years, I learned about hypnagogia ("waking sleep"), a physiological state responsible for such things (as well as the famous feeling of waking up with a great weight on your chest). Then just recently, at age thirty-one, I saw one ''again'', while out walking at night with my father. It momentarily appeared in front of a house's garage, hunched over and running parallel to our path on the sidewalk. It was in open space, it was moving, and after a second there was nothing there.

I once saw shadow people. To be fair, I had a very high fever. I tried talking to them and my mom walked in and told me I was sick and had to rest.

Arnego Moloch, from New Dawn Hollow Dusk's planned Second Arc, can animate shadows and even make them revolt against their "owner", turning the shadows of a whole army division into a field of spears which he uses to kill the whole division, and then he uses Part II of his powers: The Dead Rise. Good thing he's got horrible luck, is usually incompetent, and a DirtyCoward or ''fighting him would be virtually impossible.''
