Face at Wedding

This photo was taken at my best friend's wedding. It was after midnight and all pictures were taken with natural light. There are no near windows, or any thing for a flash to reflect, because there was no flash. When she sent it to me, I was taken aback and almost didn't want to touch the photo. I called her right away and asked her about it, she laughed and said it was a ghost. I asked her if it was in the developing and she told me that it was on the negative. When held up to the light, you can see that the images lightly cover the entire photo. What gets me, is that it isn't the end of the roll, and all of the other pictures are normal. The face that's over my head has been fading since I got it. Is that strange? It looks like there's a "D" surrounded by blue and an "I" surrounded by red, and the face looks like an "E"... Out of the head of my boyfriend (at the time), if turned counterclockwise, is a pink heart; on the back of the photo the numbers 187(a police code for murder/death) were written by the photographer, right in the middle of the heart. One of the lines is going through both my boyfriend and my hearts. Obviously we had a difficult time staying together. Out of my friend's new husband looks like a wing, or maybe a bench. Yet, when turned upside down, my friend looks like she's flying downward.
