Walking on the Ceiling: A Dream of Upside-down Meaning & Interpretation

"I woke up on the ceiling. My bed was above me. I walked on the ceiling. My feet stuck to it. I looked out the window. The sky was below me. Birds flew upside down. Clouds were on the ground. I went to the kitchen. The fridge was on the roof. I opened it. Milk poured upward. I tried to drink water. It went into my nose. I walked to school. Students walked on their hands. The teacher wrote on the board. She wrote backward. I asked, "What is happening?" She looked at me. She said, "You are dreaming." I looked at my hands. They were see-through. I woke up on my bed. Everything was normal. But I felt dizzy all day."
