Ghost hoax yes, but interesting

This has been all over the internet, but I still think it is interesting. It is now been admitted as a hoax, but I would really like to know how they did it. I certainly believe there are spirits walking around; I will swear on anything you want that I saw Ann’s dad after he passed. I have actually seen him about a half dozen times, but not since we moved. I have seen him at Possum Manor West, however. He was a really nice man, and seeing him now is not frightening at all. Ok, so most of you reading this will be sending me psychiatric hot line numbers, but I am telling you the truth. My Aunt Theresa saw her mother and my mother after they passed. Maybe it runs in the family. Hmmmm that is a blog for another time.

Anyway, here is the elevator ghost. It is under two minutes long, and the action happens in the lower right section.

I think I see her reflection in the back wall of the elevator, but how did they do it?
