We do not know the story behind this ghost picture, but we do know it shows an apparition of a man in the castle window.
Is it a fake? Looks too good to be true, to us, so we're guessing it was created and posted on the Internet for laughs.
If you look closely, the man's head just does not seem to match the light of the castle. This is important to pay attention to when you see a supposed ghost photo and something looks amiss.
To us, the shadow on the right side of the man is out of place, and his form appears a bit too big for the window pane.
