I was on my way to the doctor with rear end trouble when my universal joint gave way causing me to have an accident. An invisible car came out of nowhere, struck my car and vanished. I was thrown from the car as it left the road. I was later found in a ditch by some stray cows, coming home I drove into the wrong house and collided with a tree I don't have. The guy was all over the road. I had to swerve a number of times before I hit him. As I approached an intersection a sign suddenly appeared in a place where no stop sign had ever appeared before.
