I'm not a big believer in ghosts, etc. That being said, I firmly believe that unless it can be proven to not exist, anything is possible. And as pets stated, we have seen and experienced some weird stuff on our haunted vacations! I love the picture and to me, it doesn't really look like a reflection of light. I agree with Ally - it does look like a woman in a long white dress! Awesome picture - thanks for sharing!
