Blank Exam Paper & the Racing Clock Meaning & Interpretation

"I sat in the exam hall. The clock was ticking. The teacher gave me the paper. I turned it over. It was completely blank. No questions. No words. I raised my hand. The teacher did not see me. I looked at other students. They were writing fast. I felt so scared. What was I supposed to do? I looked at my pencil. It had no lead. I tried to write. Nothing appeared. The clock moved faster. Time was running out. I raised my hand again. The teacher looked at me. She said, "You have five minutes left." My heart pounded. I had written nothing. I started to cry. Everyone looked at me. I stood up. I wanted to leave. The door was locked. I could not get out. The teacher walked toward me. She was angry. I woke up sweating. My heart was racing. I looked at my desk. My books were there. I had studied. I was ready. It was just a dream."
