Why are you not on the wall, clock?

I am really struggling to understand why this clock is NOT on that f****** wall! One of my co workers and I were going downstairs to check out for the day, and we found this.. Just like that. It has stopped and nothing is really broken. The hanger on the wall isn’t touced (it’s newly painted and there are no scratches or anything)… It usually hangs in the middle top of this picture.

It could easily be a prank, but we were few people at work and none of us had really been downstairs ^^’ Is this place really haunted? Actually, I wouldn’t really be surprised..
