dream of long nighttime drive and rogue pickup

I was in a house with three other people as night fell. We had to pile into a car and attempt to make the journey to another place where we were expected. It was night and we drove cautiously down backroads that reminded me of Newmarket. At one point we saw a large vehicle coming at us. The person driving became agitated and turned the car around quickly to flee. The truck didn’t seem to pursue us and I could only make out a shadow of who sat in the driver’s seat. As we drove away, I could see the truck’s lights dimming – not just receding in the distance but noticeably dimming. It was some small piece of some much bigger apparatus – I suddenly realized this was our cargo. I got really scared for a moment, but thought with relief there’s no way we’ll ever make it.
