Lost Repeating City: The Bus, Key, & Three Clocks Meaning & Interpretation

"I dreamed I was walking through a strange city. Every street looked the same. I saw a bus and got on it, but I did not know where it was going. When I got off, I was standing inside my old school. I walked into a classroom, but it was full of people I did not know. The teacher gave me a key and told me to find my home. I opened a door with the key and found my bedroom. I looked outside the window and saw the same classroom. I felt very confused. Then I opened the bedroom door and found myself standing on the same bus. The driver looked at me and said, “You have been here all day.” I looked at the clock. It showed three different times at once. Then I looked at my hands and saw the teacher's handwriting. One sentence appeared: “You are not the one dreaming.” Then I woke up."
