A very disturbing but true thought came to me

A very strange dream occurred to me, or maybe perhaps it only seemed like a dream to me, because it might have been a very vivid thought; It essentially told me: "You have conquered grade school. But there are things that are still unsettled, both from middle school and High School. You must reverse things, or else, you will only experience misery and torment." It has since dawned on me: this event of my life, it has told me something that's true. What am I to do now?
