Ursula K. Le Guin's The Lathe of Heaven

Set in a dystopian, near-future Portland, Oregon, in the year 2002, the novel depicts a world crippled by catastrophic climate change, stifling greenhouse warmth, relentless rain, overpopulation, and severe resource depletion. The story follows George Orr, whose 'effective dreams' possess the subconscious power to retroactively rewrite reality, history, and memory. When his ambitious psychiatrist, Dr. William Haber, uses a neuro-technology machine called the Augmentor to manipulate Orr's dreams for utopian ends, the setting itself becomes a fluid, volatile battleground. The physical environment constantly morphs—from an impoverished, smog-choked Pacific Northwest metropolis into a sterile, totalitarian collective, a besieged world facing alien invasion, and finally a surreal landscape where fractured timelines converge. Le Guin emphasizes this ever-shifting setting to explore ecological hubris, the perils of forced progress, and the Daoist philosophy of living in harmony with nature.
