If you have dreamed of going to high school again in your dream: You are not doing it right, you should focus on whatever you want to progress in or whatever inspires you. To read high school again in a dream indicates that a person whose education is interrupted or who is not satisfied with his profession today will take action for the sake of realizing his ideals. We can interpret that the person should tidy himself up and it would be good for him to concentrate on his work.
