Native Korean word (고유어) with roots in Old Korean. It has carried both the literal sense of a sleeping dream and the figurative sense of aspiration for centuries, appearing in classical poetry and proverbs alike.

In Korean culture, certain dreams — especially ones involving pigs (돼지), tigers (호랑이), or dragons (용) — are considered 태몽 (taemong), auspicious "conception dreams" believed to predict a child's future character. Koreans often discuss and interpret dreams more seriously than many Western cultures do. The word 꿈 also appears in the common encouragement **꿈을 이루다** (to achieve one's dream), a deeply motivating phrase in Korean schools and workplaces.
