Dream of injured, shopping

I was shopping with my little sister. We were in a furniture store with all white furniture and glass walls and we were bouncing on the couches when I realized I was late for my SAT. We walked out of the store and I began to walk down the street towards CSU Easy Bay to take my SAT. A man was walking his sheepdog on the street next to me. Suddenly, the sheepdog broke off its leash and tackled me on the sidewalk. I was not injured, but I got up and decided that I was unfit to take the SAT and went home.
