How does Kenzaburo Oe use imagery in A Personal Matter?

Imagery:

"Bird fled the apartment with his eyes on the floor, fled down the stairs, fled through the hall, straddled his bicycle and fled everything behind him. He would have liked to flee his own body. Speeding away on a bike, he felt he was escaping himself more effectively than he could on foot, if only a little."

"An ugly baby with a pinched, tiny, red face covered with wrinkles and blotchy with fat ... its mouth was wrenched open in a soundless scream ... the skull was buried under a mound of bloody cotton; but there was no hiding the presence there of something large and abnormal."
