简介：One a bright spring day before a school trip, Semi, falls asleep on one side of the classroom, and suddenly awakens in tears over an ominous dream. She runs to Ha-eun, who is in the hospital after injuring her leg in a bicycle accident. Semi and Ha-eun are best friends. The film depicts a special day between the two. A spring day, puppy love, jealousy, friendship, small misunderstandings, shameful confessions, anxiety and wacky wit, red nose tips and ears, or the heels and dead skin cells in dreams, the verdant hill behind the village and the yellowish sunset—every small thing that makes up the world gathers up here and creates an unexplained and brilliant atmosphere, completing a kind of dreaming vision. The Dream Songs is full of vitality even in its sad moments.
