While the poem is not necessarily grounded in a physical setting, the speaker does describe several aspects of the natural world throughout. The first stanza takes place in an abstract, dream-like realm marked by the speaker’s slumber. However, in the second stanza, they describe the “earth’s diurnal course,” eliciting mental images of night and day, as well as the planet’s rotation in and through space (7). Then, in the final line of the poem, the speaker references the rocks, stones, and trees buried in the earth. Even this sparse description of nature as a setting grounds the otherwise free-floating mental space established in the first stanza.
