Red Room

This might be the creepiest photo I have ever taken.
I was shooting through a window in the Joule Hotel towards the abandoned building across the street in downtown Dallas. There were no lights on in any of the rooms from what I could tell.
After taking several very shaky 25" exposures (I had had a few beers at this point.. crippling my ability to hold anything steady), I noticed there was a red glow in one of the rooms.
What the what? Is there a brothel in there? Why the red light? Or maybe I should ask 'why the red windows?'

I'm scared. Hold me.
