Answer:
In the poem dreams the author uses words such as "migrations, sand, and the tail of the comet" to provide imagery of a dream. This specific word choice gives a melancholic tone that can be found in every paragraph of the poem. Each of these paragraphs mentions something someone misses. She says she misses her lover and her father waits eternally for someone. The nostalgic tone can be found in the first paragraph of the poem when she says: “where the children we were, rock in the arms of the children we have become” and other lines like "his smile still burning there like the tail of a comet that just blazed by". This word choice impacts how one may view the tone of the poem- nostalgic or sad and other emotions of resurfacing something missing.
Explanation: Hopefully this makes sense to y'all. I took answers in which asked for the tone and the word choices overall meaning and made it sound smart. lol
