American ghost at Johnson's

I was in my second year in College. My boardmates decided to go ghost hunting in the University we attended. We explore the University, taking pictures everywhere hoping that a ghost will appear in the picture. At first I did not believe that the white images on the pictures were real. We went to Johnson's and we also took pictures there. The picture that was taken at Johnson's made me believe more that ghost are really real. On that picture was a head! Yes a head of a man, an american I guess, smiling. It's so clear. He's smiling. If only that picture that was saved on the computer did not dissappear, it would be an evidence.
