I had a interesting dream last night. I dreamed that I took part in a race. At first, I could not run very fast and fall behind. So I didn’t lose heart and kept running. All the students on the playground cheer me on, “Come on!” I was so encouraged that I ran faster and fast till I caught up all the other runners. I felt as if flying like a superman. In the end, I got to the finishing line at 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!
