In Jonathan Lethem's novel "A Gambler's Anatomy," a character named Bruno experiences a disconnection from reality, as suggested by the phrase that his brain might have parachuted over the Atlantic. This vivid metaphor illustrates Bruno's mental state, implying that he is lost or disengaged from his surroundings, possibly due to the high-stakes world of gambling he inhabits.

The story dives into themes of chance, consciousness, and the uncertainties of life, using Bruno's disoriented mind to reflect the chaotic environments and decisions faced by gamblers. As he navigates through this world, readers are invited to ponder the balance between control and randomness in both gambling and life.
