How does Angela Y. Davis use imagery in Angela Davis?

Examples of Imagery:

"But tonight the way seemed strange, full of the unknown perils of being a fugitive. And there was no getting around it - my life was now that of a fugitive, and fugitives are caressed every hour by paranoia. Every strange person I saw might be an agent in disguise, with bloodhounds waiting in the shrubbery for their master's command. Living as a fugitive means resisting hysteria, distinguishing between the creations of a frightened imagination and the real signs that the enemy is near. I had to learn how to elude him, outsmart him. It would be difficult, but not impossible."
