The definition allows both true and false imaginative statements, because imagery can move us independently of literal truth value.
True image: “After rain the scent of earth spread,” if it describes an actual event.
False but possible: “The entire valley filled with roses overnight,” imagined rather than reported.
Literally impossible: “The sun held its rays in a closed fist,” personifying the sun with a human hand.
These are supplementary examples of possible poetic matter; they do not turn imagined descriptions into verified facts.
