Bjerre believed that the workings of the conscious mind were more important than those of the unconscious, and felt that Freud placed too much emphasis on an individual's sex life.

Among his written works was an influential book which theorized on the recurring cycle of "psychic death and renewal" called Död och Förnyelse.

He wrote a biography on Friedrich Nietzsche, and is remembered for his written correspondence with Freud and Carl Jung.

In the novel Bravinger portrays Andreas Bjerre's death from suicide, leaving a note for his wife Madeleine and for his mother.

His brother Poul, for whom Andreas had often expressed great hatred in his diaries, is portrayed as refusing to accept that it was suicide.
