Plato said: The real world only exists in our imagination. Probably each of us has had such doubts: maybe this world is designed for me; maybe everything never existed when I couldn't perceive it; maybe One day I will wake up. Maybe the world is infinitely nested, maybe the truth cannot be touched. I think, therefore I am, but who knows? Maybe worldly happiness comes from ignorance—— However, it is precisely because of the uncertain unknown, That's why it has such a charm. This is a story where science meets legend, and fantasy becomes reality... Probably.
