Blended perception, also known as synesthetic imagery, is a poetic device that fuses multiple senses within a single description—such as “a blue note” (sight + sound) or “bitter cold” (taste + touch)—to evoke a more immersive, transcendent, or disorienting experience; rooted in neurological synesthesia but used artistically, it challenges conventional sensory boundaries and is prominent in Symbolist and Surrealist poetry to convey complex emotional or mystical states.

Blended perception (or synesthetic imagery) fuses multiple senses in a single description (e.g., "a loud color" or "bitter cold"); rooted in neurological synesthesia but used poetically for vivid, disorienting, or transcendent effects; prominent in Symbolist, Surrealist, and Romantic poetry (e.g., Baudelaire’s "Correspondences"); students should distinguish it from simple metaphor and explore how it challenges perceptual boundaries; related to "cross-sensory imagery" and "unconscious pictures."
