What is the author's style in Juneteenth by Ralph Ellison?

Figurative language is a technique imposed by Ellison in Juneteenth to interrupt the order of his storytelling. The novel is composed of the linear story of Bliss, Hickman and Sunraider. However, the literal use of language to explain their history is broken up by dreams and memories that are brought to life through hyperboles, similes and ironic visual constructs.
