Vicksburg Anomaly Ghost Picture

Wes Robinson sent us this unexplained anomaly he captured in Vicksburg. Was it caused by light, flash reflection off of a flying insect, or is it a ghostly energy that he was able to record? Wes saw it coming, so it most likely was something paranormal:

"I saw this come thru the room and wished I had the camera on, it came back the second time, it is in the Shirley House in Vicksburg, Mississippi."
