While sleeping, I suddenly found myself sitting on the piano and playing a song. Suddenly everything became blurry and strange. It was clear that the piano lid was closed but I could still press the keys. My head fell onto the piano and it made a long, unpleasant piano sound. It seems like at that time I said "I can't play E without CH", I don't understand what I wanted to say at that time. When my whole body fell off the piano bench, I woke up at school at noon, oh yeah, I was taking a nap at school. I intended to lie down a little longer to wait for the lunch break to end, but I suddenly felt someone put their hands on both of my shoulders from behind, and the problem was that I was lying with my back against the wall. A creepy laugh rang out. I didn't know what to do, so I quickly pushed my elbow back. The laughter and the feeling of being held on my shoulder disappeared, and my eyes were no longer blurred.
