Spooky or What?

This is a shot I took today in Glasgow's Necropolis graveyard. It was brightly sunlit, but cold.

I took a few shots and was going to use another - BUT, if you zoom in on the gravestones, in approx. the centre of the shot, there's a dark head/shoulders image which can be seen directly above a gravestone.

I certainly didn't notice it when I took it - but who knows???????
