Dorothea Puente Murder House: Mystery Movement

After Aaron and Zak have a leap of logic and accuse Billy of vocally attempting to kill Zak with a pillow, Arron and Billy leave Zak downstairs on the bed. Aaron and Billy split up, with Billy staying downstairs in front and instructing Aaron to go upstairs. Aaron doesn't want to go up there alone, but reluctantly proceeds up the stairs. Not sure when Billy achieved the 'order Aaron around' rank.

Moments later from a static camera in the hallway we see Aaron laying on the bed in the "Death Room". In part, Aaron asks, "Are parts of your body still in the floor"? At which point Aaron hears a creak and says, "I just heard something in the room".

At this point they immediately switch the view to a different static camera, presumably to show the view of where the sound originated from at that very moment. At the bottom left there is a single thick cushion chair facing an open door. The moment the view is switched, if you look closely, the shadow on what appears to be the back of the chair moves. This same scene is shown a couple of times to establish the link between what Aaron heard and the empty room.

Aaron is suppose to be alone upstairs. The side-by-side view of Aaron and the other room shows Aaron didn't move his camera, or more specifically, the light on the camera. But even if Aaron did move the camera, I'm not sure what would be blocking the light in order to cast a shadow all the way over to the chair.

I'm not saying it's paranormal. Taken at face value, they didn't debunk the movement or even seem to notice that there was movement.
