Waterpark Ghost Picture

Tina sent this possible ghost picture of what looks to be an energy with almost a head-looking thing above the bed at a waterpark resort room. Freaky...we can't explain it. Was it the camera malfunctioning? You decide.

"Last February, we went to a waterpark in Ohio. This was taken at night when my son and his friend were sleeping. We thought it would be funny to get a picture of them two sharing a bed after a hard day of swimming. We did not notice this until we developed the picture. The boys freaked out and do not like to look at this. This is not smoke - no smoking in rooms (allowed). If you can explain this, please do!"
