Dream About Anxious Waiting Room Dormitory Black And White Movie

I kept going in a waiting room that was also a dormitory where everything every kid was in black and white. It was a movie of an anxious person. At school I learn that my teacher is really young. The main character of the movie becomes extremely anguished and the movie shows a parallel with what makes her anxious. She was bald. It was an unbearable anxiety. I remembered I was told it was one of the most anxiety inducing movie so I stopped watching.
