Real World of Virtuality and Reality

What is true? What is fake? How can we clearly distinguish between true and false, false and false? Then could the true also be false? I have no idea. Reality? False? Is all this just a dream? Was it Zhuang Zhou dreaming of a butterfly, or was it a butterfly dreaming of Zhuang Zhou? Everything that is obviously true cannot be true anymore, so why can't it be false? I have no idea. In the end... Still, I don't know. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
