Believe In Ghost?

I was at my senior prom when I took this picture. A few days later, after getting the picture developed, my friend noticed something odd in the back ground. At first, I didn't see it at all, and I had know clue what she was talking about, but then she said, "Lookn harder", pointing it out to me. I still couldn't quite make out what she was referring to, but as I studied the picture, I noticed a figure that appeared to be a man standing behind me. Maybe there was and an ink problem when we printed out the pic. Maybe the back ground lights and the glare from the camera created, what looked like, a face. And maybe it really COULD'VE been a visit fromt he supernatural world, but the only thing I have to say is...UH, CREEPY!!
