Something Stopped Me on the Trail

I was hiking alone on the San Francisco Peaks, maybe two miles out from the trailhead, when everything went quiet. Not the normal quiet of altitude and pine trees. Something else. I stopped walking. I do not know why. I stood there for probably three minutes without moving, and I had the clearest sense that I was not alone, and that whatever was with me was not indifferent to me. Then the wind picked up again and I kept walking. I have not stopped thinking about it since.
