TPR cheating dream (from June 28)

I'm somewhere watching CCTV. I'm not sure what's going on exactly, but some crime is on the tape, and I know where it is.
At The Princeton Review (where I work), the other teachers know that I've seen the CCTV tape and know about the crime; they are guilty of what I've seen. I've also seen other forms of dishonesty, such as giving children answers for their tests. I don't say or do anything, but they know that I know.
Eventually Audrey (my boss), followed by many other teachers, all wearing the black TPR polos we all have, burst into my room without saying anything, looking sternly at me. My face flushes. I'm afraid. Then a fat, ugly, mean teacher says "We're here to have the students take the tests again." Now that they know their dishonesty had been revealed, and for fear that I might tell someone, they are going to have the students take the test again to get an honest result. The students fill the desks of my classroom after this is announced.
They tell me I can go, that they will take care of the test, but obviously I want to stay, to keep them honest; how will I know they just won't cheat again? I'm being shuffled out of the classroom as they hand out the tests, and I know that it's wrong and I should stay, but they're herding me out like a sheep.
I say "You can't treat me like a--" but before I can say "child", the fat teacher, with a stony face says "uh-huh, ok" as if I'm a whining toddler whose words are insignificant. She shuts the door in my face.
I walk away from the classroom and into the labyrinthine academy. The halls turn in many different directions and there are classrooms everywhere. I try to glance in at a few of them. My youngest brother Cian is in one class. I see him answering a question, then writing something, then leaning over his desk, with his eyes tied to his teacher's face with a string. He doesn't see me. He's a good student, I'm proud of him.
