Wales Ghost Picture

Anthony sent us this interesting picture of what looks like a face in a castle gatehouse window:

"I was on holiday in Wales earlier in the year and we visited a castle which belonged to a famous Victorian slate mining family. The picture of the main gatehouse has a window to the right in which, there appears to be a figure."

Some people believe this white face is not curtains or reflection, but a ghost in the gate house window.  Yet, other people see a face to the right of the white face, turned sideways to the right.  Do you?
