Who is The Psychoanalyst from The Poetics of Space and what is their importance?

The Psychoanalyst in Bachelard's work is a scientist of the mind, who intellectualizes the poetic image. The psychoanalytical approach tries to understand and interpret the image. In order to make sense of an individual, the Psychoanalyst typically uses images such as locks and keys that appear in dreams as symbols of sexual intimacy. A psychoanalyst who "understands" according to Bachelard confuses a poetic image with the context of his interpretation.
