Dream About Driving Out Of Control 8

I had a dream that I was going for a drive somewhere. I don't remember where I was going, but I had a location set in my GPS. As I was driving, I remember I had about a mile and a half left until I had to make a turn and the next thing I know, I remember being very deep in thought about something. I don't remember what I was thinking about, but I remember feeling myself thinking in the dream. After I had snapped out of it, I had realized a lot of time had passed and I didn't know how I had driven so far without being fully conscious and I didn't know where I was and my GPS kept telling me to make a U-turn to turn around. I was also behind this semi, it was a small semi, carrying a container. I don't remember what it was carrying in the container but it had black smoke coming out of the exhaust and in all it was just surrounded by black smoke. It was swerving all over the roads and it almost flipped over about 15 times. All the other cars had slowed down because of this semi and I was trying to brake as well, but my brakes weren't fully working. My car was only slowing down a little bit. I also must have been sleep deprived based on all of this because I had in this moment just realized that I didn't bring my glasses, which I can't drive without, so I could barely even see my GPS. The semi was getting more and more out of control and for some reason I wasn't slamming on my brakes. I was still just easily trying to slow down and my face was relaxed even though internally I was very scared. But finally when the semi braked, my car was going too fast for me to stop at the same speed. The fear instantly set in is my car got way too close to the semi and I woke up immediately; breathing heavily, before any impact was made
