Back then, my “something like insomnia” went on for a month. I never really got to sleep that entire time. I’d go to bed at night and say to myself, “All right now, time for some sleep.” That was all it took to wake me up. It was instantaneous—like a conditioned reflex. The harder I worked at sleeping, the wider awake I became. I tried alcohol, I tried sleeping pills, but they had absolutely no effect.

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 wide 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.

This 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 dinner 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.

And then, when night came, the intense wakefulness would return. I was powerless to resist it. I was locked in its core by an enormous force. All I could do was stay awake until morning, eyes wide open in the dark. I couldn’t even think. As I lay there, listening to the clock tick off the seconds, I did nothing but stare at the darkness as it slowly deepened and slowly diminished.
