How does Tom Robbins use imagery in Jitterbug Perfume?

Imagery:

"As the afternoon progresses, our shadows grow longer. At night, in the dark, we become our shadows."

"King Alobar did not sleep at all. He was as awake as the guards at the gate. More awake, actually, for the guards mused dreamily about mead, boiled beets, and captive women as their eyes patrolled the forested horizon, while the kind was as conscious as an unsheathed knife; coldly conscious and warmly troubled."
