Finally, as the sky began to grow light in the morning, I’d feel that I might be drifting off. But that wasn’t sleep. My fingertips were just barely brushing against the outermost edge of sleep. And all the while, my mind was awake. I would feel a hint of drowsiness, but my mind was there, in its own room, on the other side of a transparent wall, watching me. My physical self was drifting through the feeble morning light, and all the while it could feel my mind staring, breathing, close beside it. I was both a body on the verge of sleep and a mind determined to stay awake.

The incomplete drowsiness would continue on and off all day. My head was always foggy. I couldn’t get an accurate fix on the things around me—their distance or mass or texture. The drowsiness would overtake me at regular, wavelike intervals: on the subway, in the classroom, at the diner table. My mind would slip away from my body. The world would sway soundlessly. I would drop things. My pencil or my purse or my fork would clatter to the floor. All I wanted was to throw myself down and sleep. But I couldn’t. The wakefulness was always there beside me. I could feel its chilling shadow. It was the shadow of myself. Weird, I would think as the drowsiness overtook me, I’m in my own shadow. I would walk and eat and talk to people inside my drowsiness. And the strangest thing was that no one noticed. I lost fifteen pounds that month, and no one noticed. 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 that 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.
