Let me leave it posted a little while before I point it out. In the meantime, I'll tell you only that it's very subtle and to the right of the dark area.
Very subtle - at first I didn't think it was anything but then it started to creep me out. In the dark rectangle at the end of the corridor - along the right edge - just over half-way up.
[image deleted] Here's another shot & I don't see anything. It's only in the one photo. It's probably nothing but it sure gave me the heebie jeebies when I first saw it. My buddies think I'm crazy but you never know...
Exploring an abandoned factory with some buddies I took a bunch of photos with my phone. Although the place was creepy I didn't see anything unusual at the time. Later when looking over the photos this made my blood run cold. Do you see it?
