The speaker wanders through a field and comes upon a large crowd of golden daffodils fluttering in the breeze beside a lake under trees. There were thousands dancing and tossing their heads in a lively dance that outdid the sparkling waves of the nearby bay in merriment. Though the speaker initially only gazed upon the daffodils, they have since brought the speaker joy, as the memory of the flowers often appears in their mind's eye during quiet, pensive moments of solitude, filling their heart with pleasure and a sense of dancing along with the daffodils.
