Yeah that looks weird. Looking closer though it's just two circles of dirt on the camera lens.
Above that though, slightly to the right, looks like a person (and not very ghost like), leaning on the fence.
Hmm you might be right, but try to look at the other pics.. There is no dirt at the lens
But anyway - it's still 100% creepy, and obviously the shape by the column is definitely not a normal person..
If it is a night club, I'm sure: I'll NEVER enter..
