This picture was taken of me jumping on my trampoliene in my backyard (Glen Ellyn, IL, USA). A picture of me was taken just a few seconds prior to this one, and there was noting abnormal in that one. Thats not the case for this one, though. My friend told me it could be ectoplasm or something, and I was just curious what other people would think. And by the way, there was no bon fire or smoke of any kind at the time of this picture.
