Bright Light Angel Picture

This angel image was sent to us by Blossom. Here's her story: "I was taking a picture of the wall I just painted, and just prior to that, my mom and I were going through a rough day. I prayed that God would send angels down to protect us. This was taken about an hour later. That is the north side of the house, no sun at all."

Is this a possible photograph of an angel...a spirit in someone's living room? We have few details about the image. If it is supernatural, then would this have to be an angel? Isn't it plausible that a human spirit could manifest in this manner? If so, we would certainly not call this a ghost but an enlightened spirit of maybe a friend or family member who visited the household in a time of need.
