Dream 9?

In some sort of school environment, where a big-haired incredibly critical teacher was constantly evaluating everyone, and seemed to have an especially low opinion of me and my work. I never actually got really angry at him though, just a little annoyed when he started personally attacking my behavior in addition to my art, saying that since I always sat next to this one girl our work was a copy, but then I shot back something about no art being original but he just kept going.
