Dream About Car Collision On Highway

I was driving my friends car that I use everyday and was on the highway going to work when out of nowhere the car spins out of control but I quickly maintain control. That is until the person in front of me slams on his breaks and causes a 4-6 car collision. I got out of the car and next thing I know I see two cars go flying over all the cars cuz they were going high speeds. The cops show up and I explain to them where I was goin and what happened to my knowledge. I then see my buddy coming down the street and I start walking towards him when all of a sudden I get lightheaded and collaps to the ground on all fours.
