Disembodied Head Ghost Picture

"I am sending you a photo I took at my house with a 35mm disposable camera about 11 pm at night. I live in a house which I think was built on an earlier house or barn. I have found signs of an early blacksmith's shop in our back yard. We have heard many voices in the house as well as shadows and music that plays very softly in the middle of the night. We were doing a remodeling project in the basement - I was taking some photos of my progress. This picture is from the finished computer room. When I had the photo developed I noticed a blur in the upper right hand corner in the window. When I looked closely I saw this eerie disembodied head which looks like either an old man or woman."
