ghost captured in a mirror?

Shocking ghost photo! Tell me what you see in the middle of the window? The night I took this photo was terrible because the neighbor's son was dying and everyone was sad. I maked this photo because photographers like to play with mirrors. And as I was watching this pic I saw what you see now. Is this a ghost? After discovering this I watched the window but there was no figure like this in the little waterdust on the mirror. What was haunted? The window or the camera? Or only hysteria?
