I dreamed that I failed in the senior high school entrance examination.

Dreams are illusory. There is an old saying in China: Think day and night. You should be too anxious to dream that you failed in the senior high school entrance examination, which led to this dream. It means that you are thinking about your score during the day. Even if your grades are not ideal, it is only the beginning of your life. You still have a long way to go. It's nothing. As long as you work hard, you still have a chance. You shouldn't have too much pressure. Maybe your score is not what you dream, and maybe there will be a good result. Face it when the score comes out!
