This story on
OddStuff states that a man has taken a picture of what is, apparently, a ghost. Here are the pictures:

Photoshop? Cloud? Something else?
To the OP and various comments in other posts:
I think the 'fold' is the string for the blind. Which means that the image is either a little behind the pane, or a reflection in the pane.
The shadows in the image do not fit the direction of the sun. (Of course, ghosts may not cast shadows, but there ARE definitely shadows in the face image)
Someone said that the composition is improbable for a casual picture. I don't quite agree; it is certainly unusual for an amateur photo, as most would take close-up of the girl, making her legs look big and having only half of the sign on the post office in the picture, but I actually see this one as a very nice composition, with the girl moved to the side, so a portion of the building is seen fully.
What do I think the image is? Probably a reflection of clouds, possibly with the face-like feature 'improved' by a picture editor of some sort. The colors and the general shape of the image corresponds closely to the notion of a reflection of a cloudy sky. The face in unusually distinct for a cloud image, but far from impossible. - Or some enhancement was done.

ETA: If you look closely at the face in the image, it is actually not as good as it seems. The proportions are not good; on the average human face, the eyes are normally on the horizontal centerline of the head. The man in this image has a very low forehead and skull, almost ape-like proportions. Also the pesrpective is wrong: we see him face on actually from slightly above, but the image is actually on the second floor, where we should see the face from below.
