Desire.

“No one in my family, not one of my friends or classmates realized that I was going through life asleep.
It was literally true: I was going through life asleep. My body had no more feeling than a drowned corpse. My very existence, my life in the world, seemed like a hallucination. A strong wind would make me think my body was about to be blown to the end of the earth, to some land I had never seen or heard of, where my mind and body would separate forever. ‘Hold tight,’ I would tell myself, but there was nothing for me to hold on to.”
