Hello! I currently have a rough but interesting idea for an SCP: a final exam that generates itself within a university, and tricks students into taking it, recreating that bad dream I think we all have had at some point of taking an exam on a subject you know nothing about.
At first I was thinking that this class would alter records and memories to trick people into thinking this class already existed, but I think this might be too overpowered to make for a good SCP. Perhaps the professor administering the final simply has a cognitohazardous field that makes students think this, but I'm not sure what his motive would be.
I also want to incorporate some kind of nightmarish element into the exam, even though exams are already nightmarish enough as it is.
Thoughts?
