Darts Ghost Picture

"We were at my friend's house playing darts. I wanted to see if I could get some shots of one of my friends throwing darts and capture the darts in mid-air. Well, I got some shots. Then I got this one. Nobody was smoking at the time, because that was my first guess; but then we looked closer and thought we saw a head by the string. I have a digital camera, so I was taking shots and I took one before this (with no mist). The timer said 10:20 and about 19 seconds, and then this picture was taken at 10:20 and about 23 seconds. Somebody figure that out, because we can't."
