During my Paranormal Investigation and Spirit Communication classes, we often set up equipment to see if we catch anything. On May 26, 2011, we set up motion detectors and a trap camera in the hallway outside the lecture room.
The motion detectors went off several times with no explanation, and the trap camera was triggered, taking the following photo:



There is a circular shadow area high up on the kitchen wall. There is nothing on the wall there, and nothing that casts a shadow on that spot.

Ghost Box Recordings from that night:

Can ypu tell us your name? Response: George
