How does Audrey Couloumbis use imagery in Getting Near to Baby?

Imagery:

"A thin rim of orange-red, so deep and strong my heart almost breaks with the fierceness of that color. Moment by moment, there is more of it to see—so hot and bright, I cannot look but at the edges."

"That sad feeling I have hardens into a mad feeling and I don't think I'll ever get down off this roof. I'll stay here till kingdom comes."

"When I looked away, I could see seven burning suns coming up all around me. But I kept needing to look back. It was like my eyes were hungry for the sight of that brilliant light."
