The Lathe of Heaven

Teachers and parents! Our Teacher Edition on The Lathe of Heaven makes teaching easy.
Iahklu’ is a word in the language spoken by the Aldebaranian Aliens Orr creates with one of his effective dreams. Iahklu’ has no direct English translation but seems to refer to the act of effective dreaming. Orr first encounters the word in one of his effective dreams, when an Alien gives him cryptic advice about what to do when his effective dreams become dangerous. Orr later asks an Alien named Tiua’k Ennbe Ennbe to define iahklu’ for him, but Tiua’k Ennbe Ennbe explains that the word is “incommunicable” and offers Orr the Beatles record “With a Little Help from My Friends” in an attempt to convey the essence of iahklu’ without language. That Tiua’k Ennbe Ennbe tries to teach Orr about iahklu’ with a song about friendship, love, and unity suggests that iahklu’ has something to do with beliefs about interconnectedness, universal balance, and compassion, which are essential to the Aliens’ philosophy of life on Earth and in the dream world.
