Dream about driver abandoning car over cliff!?

Alright, I had a dream last night where I was with my dad and we were traveling early in the morning. Then out of nowhere, before we came to this bridge, the breaks on my car went out. Instead of going on the bridge my dad drove off this cliff and we went flying off the side. We sailed over some water and my dad tried to jump for his life but hit the ground. I was stuck in the passenger side when I decided to wake up. How could this be explained? p.s. The only light that comes on in my car is my "brakes" light when I start it. This dream might scare me to get my brakes checked out... I am 21 and dreams like this occur once a week where I am just shocked into waking up.
