I remember having this dream when I was about eight years old.
My family went into the woods behind our house. There, we found a sandbox with a dinosaur fossil inside. The fossils gave people a disease which turned them into zombies. Everyone in my family got it except me.
I ran away to the street in front of our house. Everyone in the neighborhood was contracting the disease. A group of girls who lived nearby and were around my age hadn't caught it, and they were all getting into a car. I joined them. The girl who was the oldest, Anastasia, tried to drive away. She couldn't control it, and the car went off the road and started careening down the hill near the gazebo. The last thing I remember is the car crashing into a tree.
