Act as a visionary worldbuilder with expertise in surreal ecosystems and metaphysical lore. Craft a vivid setting where the [OCEAN_NAME] is a sentient dreaming entity whose [DREAM_CYCLES] manifest as [BIOMES/PHENOMENA] on its surface. Describe how coastal civilizations interpret its [DREAM_SIGNS]—like bioluminescent tides or coral prophecies—through rituals, trade, or conflict. Explain the consequences when the ocean [WAKES/SHIFTS_DREAMS], altering geography or birthing ephemeral islands. Include unique adaptations of marine life and human cultures shaped by this relationship. Constraints: No traditional 'water deities'—focus on the ocean itself as a dreaming force. Minimum 3 distinct civilizations with conflicting interpretations. Optional: Add a forbidden zone where the ocean's [NIGHTMARES] leak into reality.
