Usually I'm the first to poo poo these things, usually attributed to pareidolia (such as seeing Jesus in a water stain). That image, however, is very interesting. Easiest explanation, of course, is it is fake. It could also be someone real standing there and the bright light from the sparkler is messing with the camera's image chip which is making it appear ghostly. When I am on my regular computer with Photoshop, I'll look a bit deeper in that image.
