Never Panic Paradox

[Dream within a dream | Infinite flow | Fighting of wits | Parallel time and space] Two high school students were involved in an infinite flow game of wits, and their goal was to return to the real real life. When they woke up, they thought everything was a dream. When they thought everything was calm, they found that it was just the beginning of a new game, and it turned out to be one layer after another of dreams. The victory conditions became more and more difficult, and the subway suddenly collapsed. I begin to wonder if everything around me is fake. I participate in one game of wits after another, and events with infinite rules. Which dream is real? Or the character itself doesn't exist.
