This uses an analogy of the song, "Row, Row, Row your Boat." The analogy is between the whimsical and the metaphysical POV. The inspiration for the poem came as I was watching a movie about Star Trek 5: The Final Frontier (watch attacked video) where Kirk, Bones, and Spock are singing the round, Row, Row, Row your Boat. Spock being the logical one says to the Captain, "Life is not a dream."
