Travelling through the forest in Mexico, I reread Ursula Le Guin’s The Word for World Is Forest, which is set on a planet covered with forest. The inhabitants of the planet have trained themselves to master their dreams. For them, dream-time and world-time are equally real. At some point, a group of earthlings arrives, intending to colonise the planet. To the locals, the invaders’ dreams seem like those of a 3-year-old with no control and no awareness. Also, the earthlings use hallucinogens that send their dreams out of control.
