How does Thomas Pynchon use imagery in The Crying of Lot 49?

Example of Imagery:

"As if their home cemetery in some way still did exist, in a land where you could somehow walk, and not need the East San Narciso Freeway, and bones still could rest in peace, nourishing ghosts of dandelions, no one to plow them up. As if the dead really do persist, even in a bottle of wine."
