Mysterious World

I have lived in this world for 18 years. This world is no different from my previous life, but in the past few days, I can always see a looming ball tied to the sky. I asked many people and they couldn't see it. My parents had weird smiles and strange eyes, but I didn't say it. Maybe this was not a good thing. In my dream, the ball tied to the sky fell down, and the whole world turned red. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
