A flower in a dream usually points to beauty and potential that's still fragile -- something growing that hasn't fully proven itself yet, whether that's a relationship, an idea, or a version of yourself. A flower in bloom can reflect confidence in that potential, while a wilting one may name a worry that it needs more care than it's getting.
