Do you think this could have been influenced by the old "Boy in the Corner" and "The Man Behind the Door" legends? I see some distinct similarities and if the filmmakers ever spent time in the Memphis area, they might have come across the similar story/concept. It could be that this story is simply a generalized psychological phenomenon that is born from our anxieties and fears of the dark. Kind of like when you think you see something move out of the corner of your eye and you look and realize there's nothing there. It still rattles you. I'd be very curious to sit down with the filmmakers and talk to them about this simple yet haunting idea.
