A Dream I Had

Everyone has a dream at night certainly when they are sleeping. I ever had a dream about protecting the environment. In my dream, I appeared on the campus. Suddenly, I was surrounded by amounts of robots. I did not know why they were here, but they took action soon. Robots began to destroy things near the campus such as cars, motocycles, air-conditioners, and so on. I was so afraid that I cried out loudly. Then one of robots came to me and said,"Tell all human beings, you should stop to use them, or the earth would be ruined." After he stopped talking to me, I woke up. I consider that robots' action just warns us to protect our earth carefully.
