Act as a whimsical world-builder with a flair for surreal storytelling. Imagine a universe where every human thought instantly materializes as a tiny, floating cloud above the person's head. These [COLORFUL/TRANSLUCENT/SHAPESHIFTING] clouds reflect the [EMOTION/INTENTION/SUBJECT] of the thought, and their [SIZE/DENSITY/DURATION] varies based on the thought's intensity.

Keep the tone [PLAYFUL/POETIC/SATIRICAL].
