How is vivid imagery employed within Scheherazade's depiction of her former life as a lamprey eel?

Murakami employs a great deal of vivid imagery within Scheherazade's depiction of her former life as a lamprey eel, such as when she explains, "But lampreys have only suckers, which they use to attach themselves to rocks at the bottom of a river or lake. Then they just kind of float there, waving back and forth, like weeds" (119). The symbolism of the lamprey eel will become significant later when Scheherazade describes moving about people's empty houses in the dark and again mentions feeling like a lamprey eel.
