I had a interesting dream last night. I dreamed that I joined a race. At first, I could not run very fast and fell behind. So I didn’t lose my heart and kept running. All the students on the playground cheer me on,   “Come on!”
I was too encouraged that I ran faster and fast till I caught up with all the other runners. I felt as if flying like a superman. In the end, I got to the finishing line first. I won the race. I felt very proudly of myself. Many of my classmate threw me up into the air. Just at that time ,I woke up and found me still in bed!
