I believe that the first image is just a .. well a load of shit. The shadow in the hallway is exactly that ... looks to me as if somebody walked past outside and it was their shadow ... in the sun. I watched it at least 10 times and that's what I think.
IF u look closely at the first video, the shadow is facing us, and if u ask me, the lights were on reflecting the shadow towards us. Just leave it alone dude, let him rest in peace for fucks sake.
Can we respect the opinions of others here, please? This goes for everyone: Stating your belief is just fine, but don't try to make everyone else believe the same thing (and certainly don't insult people for having an opposing belief). It's just disrespectful.
