"It's been four nights since I've woken up to this. I begin writing down what I experienced. Were I to go back home, my friends will surely ask about it. Were I to die, I hope it will help others. Demons and monsters are everywhere, like evil ghosts. I fear them, and come nightfall I can't sleep. I wander to and fro, but I can't avoid them. The trees and the grass are also strange, unrecognisable. Although I'm a thousand miles from home, I must find a way back. This is what's most important."
here's a more accurate translation from the original, classical chinese text.
