I'm a very skeptical person and the only reason I watched this was to see how far out of control the fanatics are getting with this. The first time I watched, I conceded to the shadow theory. However, when I showed someone else for a laugh, I noticed the "shadow" was in front of the wall and had a certain degree of depth AND does not become skewed (elongated) as it should as the person moves away from the light source. It really looks to me that this "shadow' is crossing the hallway not in the room at the end, but at an intersecting hallway maybe ten or so feet in front of it. Not sure what to make of it, but we have all seen shadows and know when one looks right... and this one doesn't look right. I'm convinced this was doctored to look like a ghost or is perhaps the real deal. I'm going with no on the shadow theory.
