meaning of dream about driving

I was driving down a dirt track to town and couldn't go any further because of all the huge dead trees fallen directly accross the road. Returning home I looked out to the road and a bridge had been made over the trees and a large truck was attempting to cross. It was going too fast and skidded off directly in front of my house. The cab of the truck flipped and slammed roof down with a shocking thud. Squashing the driver dead. I grabbed my children (my husband was indifferent to my shock) and found another way into town where i was in a state of shock and i lost track of my children and woke up.
