These horses seemed to be a target for some other very fierce black horses, and as they came running in the direction where I was, I could discern their fear. They suddenly turned and went into the narrow, low opening of a very large tent, which seemed to be very stationery and stable, and if it were being built right now, a person would consider making it tall and narrow like a tee-pee, but with some wider space toward the top, like a geo-dome, and it definitely had geometrical patterns on the outside of the tent, which was neutral in color.
The horses were trembling, as they went inside the dome. It was not lit up, and they were under the cover of darkness inside this dome. All three horses then layed down next to each other, and were very still, but I could still see them trembling for fear, hoping not to be discovered. My inclination was to be protective of these horses.
