He thinks of the field of daffodils that is described in the poem.

Explanation:

William Wordsworth's "I Wandered Lonely As A Cloud" shows the speaker of the poem wondering like a cloud in his imagination. While floating among the clouds, he came upon a field of daffodils, which is a picture of perfection that gives him immense joy and calm. The flowers, with their dancing and fluttering actions leave the poet content and peaceful. He says that experiencing this scene can only give joy to the person. This beautiful and joyful company of the flowers gives only joy and happiness, even reducing the negative energy. So, whenever he feels "pensive" or "vacant', he will think back to this image of the daffodils and that will instantly lighten his mood.
