Corfu, Greece Ghost Picture

Andy Hunt of Dorset, England sent us this ghost picture taken in a tunnel at an old fort in Greece. Is it a ghost or light coming from somewhere else? We're not sure. You decide...

"My wife and I recently visited Corfu, Greece and paid a visit to Neo Frourio, an old fortress situated in Corfu town. I took many images using my Fujifilm Finepix S3000 digital camera. The image I have enclosed was one of a few I took in a series of dark corridors and passageways within the fort. This particular image shows a strange misty glow at the bottom of the passage. I was quite excited when I saw it, but I am skeptical…who knows? Maybe you can justify what it may be. The spot lamp in the middle right of the picture throws a yellowy light in the passage, but the ‘apparition’ is white in colour. Also the room at the other end was not exposed to daylight. I also did not use my flash at the time."
