One day I was at home listening to music when suddenly I felt a pain in my neck. As I tried to turn my head,
I head my neck crack. I got the fright of my life. I was so scared that I could feel my legs trembling.
"What's the matter with me?" I thought to myself.
Just then, I felt myself slapped by someone. I opened my eye and saw my teacher standing over me with an
angry look in his face. I realized then that I had been dreaming. I didn't mind getting caught dozing off
in class. I was happy what happened was just a dream.
