The similarity between a poem and a dialogue

"A poem can be dialogue, it can contain dialogue, or there can be no dialogue at all (as in many lyric poems).

Dialogue can appear in other forms of writing, and usually does in novels, short stories, plays, and in many narrative poems.

Therefore, poetry and dialogue are not prerequisites for each other. Dialogue is optional in poetry. Dialogue can appear in other forms of writing. An analogy is imagery. Poems can employ imagery but don’t have to. Imagery can be used in other forms of writing.

Dialogue is like one color in an artist’s palette, to be used as needed."
