I had a similar experience. I was low walking along a fence row trying to get on some feeding deer when I caught some movement out of my peripheral on the other side of the fence row. When I figured out what it was I started to play with it, slowly moving forward and backward. It mimicked my every move. After a couple minutes of this I realized he was stalking me. As soon as I stood up, it bolted...so did the deer!I had a coyote follow me along a trail once..it didn’t feel right at all.
