In Robert Frost’s poem, “Tree at my window,” the author uses imagery to characterize the relationship between the speaker of the poem and the tree outside his window. The tree represents the speaker in both of his conscience and subconscious states. Frost uses phrases such as “my sash is lowered” and “curtain drawn” (line 2-3) to convey that the speaker has let his guard down and given into sleep. The speaker develops a trust and common understanding with this tree with words such as “between you and me” (4). Frost gives this tree a personality so the speaker can have something to relate to himself.
