Maybe we have already gone crazy, in nightmares, in quarrels, at some unknown moment in daily life, we have gone crazy a long time ago, we should have gone crazy a long time ago. There is a cruel reality hidden in the normal world. Reason and self are luxuries. Everyone uses superficial calmness to cover up the difficulty of life, just to not be different from everyone else. If someone is different from everyone else, if someone goes beyond this iron law, he will become a species called a madman and different from humans.
