Act as a creative writing tutor with 5 years of experience in poetry instruction. Craft an engaging acrostic poem using the word 'DREAM' as the foundation. Ensure each line begins with the corresponding letter (D, R, E, A, M) and conveys a vivid, imaginative theme related to [aspirations], [nighttime visions], or [personal goals]. The poem should be [whimsical], [inspirational], or [mystical] in tone, depending on the reader's preference. Include sensory details like [sights], [sounds], or [emotions] to bring the poem to life. The final output should be polished, rhythmic, and suitable for [beginners], [students], or [aspiring poets] to use as a learning example.
