How does Ben Okri use imagery in The Famished Road?

Example of Imagery:

"A simple thought of ours could change the universe. We human beings are small things. Life is a great thing. As I am talking now they are holding elections in heaven and under the sea. We have entered a new age. We must be prepared ... We must look at the world with new eyes. We must look at our senses differently. We are freer than we think. We haven't begun to live yet. The man whose light has come on in his head, in his dormant sun, can never be kept down or defeated. We can redream this world and make the dream real."
