How does John Howard Griffin use imagery in Black Like Me?

Examples of Imagery:

"I felt the Negro children's lips soft against mine, so like the feel of my own children's good-night kisses. I saw again their large eyes, guiless, not yet aware that doors into wonderlands of security, opportunity and hope were closed to them."
-November 24, p. 114

"The transformation was total and shocking. I had expected to see myself disguised, but this was something else. I was imprisoned in the flesh of an utter stranger, an unsympathetic one with whom I felt no kinship. All traces of John Griffin I had been were wiped from existence. "
—November 7, p. 11
