I drove home just as it was dark . no one else was on the road but ahead I could see lights that looked like a tractor or grader up ahead, when I got close enough to switch my brights off the lights changed from a few dim lights to very bright stadium like lights shining into my winshield moving at the same speed I was traveling forward but moving backwards keeping pace with me, I slowed down then went as fast as the truck would go panicing. eventually in a instant the lights took off upward and away leaving a bright trail and became a point in the sky like a star
