2 of us were in the woods earlier checking for any activity. The other individual that was with me began to tell me that a while back while testing a new camera, she experienced something that sounded like it was "Rushing toward" her. It was so intense that she said it sounded like it was going to knock her over. While telling me about this experience, we both heard something coming up behind me (She was facing me - in the position she was in when it happened originally). I quickly got out of the way only to turn around and see a large branch that was hanging onto the ground bouncing up and down as if someone lifted it and let go. I snapped a black & white photo in high ISO and got this.
(Here's just the anomaly)
