A Deep & Subconscious Childhood Fear Of A Fake Devil-Like Character From A Film?

I slept very well/solidly last night only waking up a few times to use the bathroom and once from slobbering/drooling (nasty)/snoring (maybe) and maybe a dream, each time I woke up remembering part of a dream, but I would go back to sleep without thinking about them or voice recording them; and so I forgot all of my dreams except for part of the end of one dream.

I remember being inside a dimly lit multi-story building with no windows that had brownish/dark-colored carpet and I was on an upper floor I think, and I think that it was a school even though it did not look very school-like and there were not that many students; and I remember being with a small class of other students, and one of the other students was my former classmate JC and maybe a few of my other former classmates were there but I am not sure.
