The Quiet Classroom & Endless Equations Meaning & Interpretation

"In my dream, I sat in a middle row of a brightly lit classroom. Row after row of wooden desks stretched out across the smooth floor. The teacher wrote long math equations across the front blackboard with white chalk. I picked up my pencil and wrote the numbers down in my notebook, line by line. Around me, other students turned pages and took notes without making a sound. Daylight filled the large windows along the wall. I kept writing until the chalkboard was wiped clean. I watched the clock ticks, feeling calm and steady, without any strong feelings at all."
