I really do not remember much but I had to have seen this movie between 2004 and 2008. It was in color and I am pretty sure it was a movie. There is a main character girl who is in a dream but doesn’t know it, and her teacher is talking and something prompts her to stab said main character in the forehead with a pencil, but then the scene, as the pencil would go into her head, flashes to potentially scientists of some sort(?) putting something where the pencil would have stabbed, and some other characters walk by who are okay with the situation I believe.
