From a dream, I will research the concept of daimon from its historical roots in Greece and from similar ideas in other traditions. It is important to note what happened to this concept in the Judeo-Christian tradition where it was demonized. Jung, in his connection with the ancients, also quotes the term in several passages in his work and admits, like Socrates, the presence of a daimon in his life. Only in the Last Thoughts chapter of the book “Memories, dreams, reflections” does he reveal his preference for the term daimon over the unconscious term. The daimon , does not attend science, is in the tradition of fantasy and addresses the soul. The concept of the daimonfinds its place in analytic therapy when we look at a symptom as a message from the deep part of being. It requires us to pay attention to the daimon's messages that speak of designation, destiny and, in the Jungian perspective, of individuation.
