“Insomnia is the feeling of inadequate or poor-quality sleep because of one or more of the following: trouble falling asleep; trouble remaining asleep through the night; waking up too early; or unrefreshing sleep for at least one month” (“Psychology Today: Insomnia,” 2015). There are many causes of insomnia as suggested by the article by Siamak N. Nabili; among them the nameless narrator of Fight Club would have met the criteria for several: jet lag, changes in shift work, stressful situations in life, and insomnia related to high altitude (flying in the case of the narrator) (2014). “One can also acquire chronic or long-term insomnia…[causes of which] are usually linked to an underlying psychiatric or physiologic (medical) condition” (Nabili, 2014). Throughout the text it is evident that the narrator met several of such factors, which may have been the cause of his insomnia, and yet there was one more, the previously unmentioned psychiatric condition—the dissociative identity disorder. “Dissociative identity disorder is a severe condition in which two or more distinct identities, or personality states, are present in—and alternately take control of—an individual.” (“Psychology Today: Dissociative Identity Disorder,” 2014). The condition is “characterized by a fragmentation, or splintering, of identity” (“Psychology Today: Dissociative Identity Disorder,” 2014). “Usually, a primary identity carries the individual's given name and is passive, dependent, guilty and depressed. When in control, each personality state, or alter, may be experienced as if it has a distinct history, self-image and identity. The alters' characteristics—including name, reported age and gender, vocabulary, general knowledge, and predominant mood—contrast with those of the primary identity” (“Psychology Today: Dissociative
