How does Walter Dean Myers use imagery in Dope Sick?

Imagery:

"I'm sitting there watching the whole thing on television, watching my life like it was happening outside my body."

"He stopped the screen image, but I couldn't take my eyes off the still picture. I was half standing, half crouched over. I saw the Nine still in my hand. I looked up at my face. My eyes were like something wild."

"On the screen I wasn't moving, just sitting there, my eyes closed, my face twisted, like something real bad was going to happen to me. Or maybe was going to catch up with me. I didn't know which. I reached for the remote."
