I have once read a sentence that one may forget the dream that he or she dreamt just the night before. In most cases, it is true. Nevertheless, there are always some exceptions. I have had an extremely unpleasant dream which I would never forget.

The dream was about mathematics. It happened after a mathematics examination when I was a junior high school student. I hate mathematics then because of the badly strict and arrogant teacher. Consequently I did a bad job on the examination, to be exact, I failed. I was too ashamed and disappointed to say a word after I was informed of my grade. That night, I had the nightmare.

I suddenly realized that It was a math lesson. The teacher was giving the lesson and writing some exceedingly complicated formula on the blackboard. To my surprise, I couldn’t even understand a word! On the country, all the students were listening very carefully and wrote down some notes from time to time. It seemed that they can completely understand what the teacher was saying.  A cold sweat broke out on the back of my neck as I was feeling more and more anxious. ‘Why can’t I take in any word?’ I kept asking myself, but there was no answer. All of a sudden, the teacher asked me a question which seemed to be quite easy. However, no matter how hard I tried, I just couldn’t figure it out. The teacher was hastening me while the classmates were laughing at me. It was their laughing and mocking that nearly forced me to cry. All I wanted was to escape and hide myself alone.

At that moment, I woke up and realized it was just a dream. But it was too vivid to be true! My heart was still beating quickly and there was much sweat on my back. It takes me a long time to calm myself down.

I am pleased that I no longer need to learn math so that I will never do a similar dream.
