Latest Ghost Encounter in Tantallon Castle

This Photo struck the Internet today, with millions of views in the first hour published.
The eerie image is captured in a photograph taken by tourist Christopher Aitchison in May 2008 at Tantallon Castle, which sits on a rocky outcrop along the Scottish coast, east of Edinburgh. The "person" appears to be wearing an old-style greenish ruff around the neck.
Experts on the paranormal are scratching their heads over this image, showing an odd figure apparently wearing period clothes and peering from a window in a Scottish castle. The shot was taken by a tourist in May of last year and made public Friday by scholar Richard Wiseman, who received it when he invited people from around the world to send him their photos of ghosts.
