What metaphors are used in The Poetics of Space by Gaston Bachelard?

Bachelard notes that an image is not a substitute for the reality that can be perceived. The poetic image can be mistaken for metaphor in academic psychology. The term "image" can be confused with the things surrounding it that one sees everywhere, rather than as an expression of the imagination. Bachelard proposes the ability to imagine as being a major power of human nature. Imagining lets one face the future and depart from the past and reality. Foreseeing requires imagining. Pure sublimation eliminates the ability for the automatism of language to function.
