Empty School Corridors: A Dream of Lost Time Meaning & Interpretation

"I dreamed that I was walking through my old school. The halls were long and quiet. The lights were on, but there were no students or teachers anywhere. I could hear my shoes making a soft sound on the floor. I walked to my classroom and slowly opened the door. Everything looked normal at first. The desks were in rows, the blackboard was on the wall, and my school bag was sitting on my old desk. But the classroom was completely empty. I sat down and looked at the clock. It showed 10:00, but the hands were not moving. Then the school bell suddenly rang. The loud sound made me jump. I quickly walked into the hallway. I looked left and right, but there was still nobody there. I tried to find the main door, but every hallway looked the same. I opened a door and found my classroom again. I opened another door, but it also led to the same classroom. I became very confused and started walking faster. Then I heard a teacher calling my name from the end of the hallway. I followed the voice and found a dark staircase. I slowly walked down the stairs. At the bottom, I saw a small door with light coming from underneath it. I opened the door and suddenly found myself standing outside my own house. The school was gone. I turned around, but there was only an empty street behind me. I stood there wondering what had happened. Then I woke up, still feeling confused."
