Marie Darrieussecq hasn’t had a good night’s sleep for 20 years. In Sleepless: A Memoir of Insomnia, the French writer, psychoanalyst, and translator deconstructs the experience of those unending, insomniac “dead hours,” which she spends pacing, reading the work of other insomniacs, and performing nightly rituals—composing long lists of old babysitters, drinking glasses of chocolate soymilk in pretty cups, assuming Alexander technique poses—that she hopes might bring on sleep, but always fail to.

Sleepless is categorized as a memoir, but it reads more like a commonplace book—a collage of quotes from other artists who have written about their insomnia. Darrieussecq communes with them, the authors of what she calls “four-in-the-morning literature,” because the rest of the world is asleep—and even when the sleepers are awake, they’re unable to commiserate. Proust didn’t sleep, and neither did Perec; Duras was self-righteous about her inability to sleep; and Jean Rhys was an “inveterate insomniac.” The list is long and heady; one might begin to believe that sleeplessness marks a kind of intellectual superiority. Darrieussecq doesn’t dissuade her readers from the notion: Geniuses seem to be punished with this affliction.

Darrieussecq situates sleeplessness as a sort of paradoxical state of being. “When it comes to sleep we are not equal,” she notes, but sleeplessness is also the great equalizer: “real insomnia does not care in the slightest about objective causes, and it crosses all social classes.” She plays with this opposition frequently. Early on in Sleepless, a hierarchy of insomniacs is established alongside a moralizing binary of sleepers and non-sleepers. “The world is divided into those who sleep and those who can’t,” the book begins. Within the world of non-sleepers, there are two kinds of insomniac: those who experience occasional bouts of sleeplessness, in which “life’s worries continue through the night,” and those who are cursed with a metaphysical sleeplessness without reason. One group has earned its stripes more than the other. Darrieussecq asserts this binary gently, but she includes lines from many other thinkers who were keen to take sides.

Darrieussecq is a romantic—suggesting that insomnia, like writing, rests on a fantasy of the chosen—but she is also pragmatic, well aware that her pose of superiority is little more than a last refuge for the insomniac, a kind of fallow hopefulness carrying one through those dead hours.

Indeed, her memoir hopes to elucidate how sleep is core to every aspect of our culture, approaching it intellectually as well as at the terranean level. However, at times the book seems determined to assert a secondary project: the argument that an obsessive study of sleep is in itself an armor against sleeplessness, or at least leads one on the path to overcoming it.

Darrieussecq collates the ephemera of sleeplessness like an archivist or a detective. She is fueled by the quest to gain a deeper sociocultural understanding of sleep as well as the desire to understand her own sleeplessness as a consequence of something larger. She covers tremendous ground, weaving facts, personal narrative, photos, movie references, excerpts from newspapers, diaries, and novels. The book itself is a kind of scrapbook charting her path toward sleep, which it’s never fully certain that she finds.

In a section about beds and bedrooms, Darrieussecq writes about becoming a psychoanalyst in order to cure her own clinophilia (the urge to lay in bed for hours without sleeping), and to understand the Western obsession with excess and bric-a-brac as well as the proper feng shui of bedrooms. Along the way, there are interesting tidbits like this one: Beds are the only piece of furniture the police cannot seize. Another chapter seeks to understand the animal world through a nonhuman understanding of sleep, her dog’s third eyelid, and how a peaceful communing with animals might be one route to curing insomnia. Darrieussecq also dedicates several chapters to her time in Rwanda and Kinshasa (where she went to record the stories of genocide survivors), writing about how travel impacts her, an arduous journey through a dense forest, the connections between trauma and sleep, and the insomnia of the unhoused.

At times, Sleepless feels bursting at the seams and runs the risk of incongruity. Yet there is a kind of precision in Darrieussecq’s process: laying out everything she can gather on the topic of sleep, turning the subject a few degrees at a time, composing new arrangements of her fragments, courting new understandings.

Occasional bouts of insomnia turn into a lifetime of relentless sleeplessness for Darrieussecq. Sleep, or the lack thereof, becomes an obsession fueled by the dread of exhaustion that defines each morning. Her obsession becomes a project, and she turns her attention to the causes, implications, and consequences of her state of being, her condition. As one does when obsessed, she picks her insomnia apart, rooting it, intellectualizing it, recategorizing it, attempting to control it—but the obsession itself is an energy that reinforces her inability to sleep.

The average sleeper is likely to suggest a host of antidotes to the non-sleeper: less screen time, early-morning exercise, mindfulness, and bland foods. But these suggestions are often pointless; the insomniac has already tried everything.

Darrieussecq catalogs the various remedies she’s tried: hypnosis, psychoanalysis, herbal teas, light sadomasochism, several drugs, scholarship, various apps, sleeping with her legs elevated, masturbation, and cranial osteopathy—all with little or no result. Drinking seemed to help, or at least kept her placated as the mounting anxiety over another night spent awake loomed ever closer.
