Summary of the Poem
Speaker in the poem is trying to express the feeling of being clouds. Becoming a cloud is such a wonderful feeling. Wandering like a cloud floating above hills and mountain being able to witness tall beautiful yellow daffodils beside the lake are the feelings that cloud experiences. High and low winds make those flowers flutter and dance through the waves of lakes.
The speaker says that a poet could not help but be happy in such a joyful company of flowers. He says that he stared and stared, but did not realize what wealth the scene would bring him. For now, whenever he feels “vacant” or “pensive,” the memory flashes upon “that inward eye / That is the bliss of solitude,” and his heart fills with pleasure, “and dances with the daffodils.”
