Dream of girlfriend, swim

Me and girlfriend driving in the car down the road. I see the road is coming to a dead end so I go to do a u turn. I was driving to fast and didn't notice the road had dropped off to a steep hill with tons of trees. I am filled with fear that something..we will die. I manage to steer car around few trees avoiding crashing. But we hit this slope like a ramp are launched into the air. We plunge into a lake and the car is sinking fast. We both are trying to get out of the car and finally do. Swimming up I constantly looking for my girlfriend . Pulling her and so worried I will look back and she won't be there. I keep thinking we aren't going to make it but than I see light and swim faster towards the surface.
