Thank you. I have a small story about when I was at this exact location taking this photo. Just as I was setting up I could hear this small squeel or groan or something just off the right of the frame. I chalked it up to machinery but one of my companions on this excursion also heard this noise. I could see it made him very nervous but I continued with my photography. Just as I hit the shutter for this exact frame we both heard it again but clearly. It was in behind the shroud of the darkness around us but very clearly human. We immediately hit all the flashlights and shot them towards this sound. Nothing. The room was empty.
