In Jungian psychology

For Carl Jung, Hermes's role as messenger between realms and as guide to the underworld made him the god of the unconscious, the mediator between the conscious and unconscious parts of the mind, and the guide for inner journeys. Jung considered the gods Thoth and Hermes to be counterparts. In Jungian psychology especially, Hermes is seen as relevant to study of the phenomenon of synchronicity (together with Pan and Dionysus):

Hermes is... the archetypal core of Jung's psyche, theories...

He is identified by some with the archetype of healer, as the ancient Greeks ascribed healing magic to him.

In the context of abnormal psychology Samuels (1986) states that Jung considers Hermes the archetype for narcissistic disorder; however, he lends the disorder a "positive" (beneficious) aspect, and represents both the good and bad of narcissism.

For López-Pedraza, Hermes is the protector of psychotherapy. For McNeely, Hermes is a god of the healing arts.

According to Christopher Booker, all the roles Hermes held in ancient Greek thought all considered reveals Hermes to be a guide or observer of transition.

For Jung, Hermes's role as trickster made him a guide through the psychotherapeutic process.
