That's strange, I had a nightmare last night about the same thing, it was at night, almost pitch black out except for the faint glow/outline of what looked like reflections from night vision goggles on a border between either south korea, north korea or china. The troops were moving in closer and closer, they had spotted me and began firing, once the firing started I could see a massive rain of anti aircraft fire and mortar shells being fired off in the night sky.

Horrible coincidence? Or something more?
