How does Betty Eadie use imagery in Embraced by the Light?

Imagery:

"Something was wrong. My husband, Joe, had left my hospital room only a few minutes before, but already a foreboding feeling was enveloping me." Chapter 1, The First Night, pg. 1

"Then I felt a surge of energy. It was almost as if I felt a pop or release inside me, and my spirit was suddenly drawn out through my chest and pulled upward, as if by a giant magnet. My first impression was that I was free." Chapter 4, My Death, pg. 29
