How does Charlaine Harris use imagery in Dead Until Dark?

Example of Imagery:

"I had an image of Arlene's kids, playing on my living room floor; I saw myself, and I didn't look like the person I saw in my own mirror. I had huge holes in my neck, and I was lewd; I had a knowing leer on my face, and patted the inside of my thigh suggestively. I was in the mind of Rene Lenier. This was how Rene saw me."
