How does Donna Williams use imagery in Nobody Nowhere: The Extraordinary Autobiography of an Autistic?

Imagery:

"I thought I felt a whisper through my soul, everything is nothing, and nothing is everything. Death in life and life in death of falsity."

"The bare floor, wall-to-wall mirrors, the barred windows, and the hoard of untouched, unwanted dolls spoke of who I was. My mother stood there among the rejected dolls and, so she told me, cried for the first time."

The city street was a nightmare: moving walls of people, my feet surrounded by feet everywhere."
