Dream of injured

I was driving our old family van along a very curvy dirt road. My friend and his family were in the vehicle and I lost control, recovered and on the next turn lost control again and slid off the cliff. I was ok but devastated that I might have injured the others and threw myself all the way down to the bottom.I ended up in a laying in a creek. My family came to my rescue. My grandma was there but was carried inside a tent. My dad asked medical attention if I had a concusion and said I had a small deep gash on my head behind my right ear.
