I dont know what is. Tall, overcoat like a trench or duster and the hat. Likes corners and hallways and has a tendency to conceal part of his body behind a door jam or corner like someone would if they were leaning around a corner or into a door to look in.

If your like me and use courage craft and tell to get his creepy ass out of your house he will go away...then comes right back a little later.

He seems to need shadows to manifest, i see him during the day all the time but always in a shadowy corner or under a tree.
