Hey you might be interested in some stuff from CG Jung he and Freud had a falling out over his involvement with the occult.
Jung was interested in the occult even though his father pastor. His whole house got haunted just before he started to write his seven "sermons to the dead"mainly do to his encounter with the unconscious.

In November 1913, Jung commenced an extraordinary exploration of the psyche, or "soul". He called it his "confrontation with the unconscious". During this period Jung willfully entered imaginative or "visionary" states of consciousness. The visions continued intensely from the end of 1913 until about 1917 and then abated by around 1923. Jung carefully recorded this imaginative journey in six black-covered personal journals (referred to as the "Black Books"); these notebooks provide a dated chronological ledger of his visions and dialogues with his soul.[3]
Beginning in late 1914, Jung began transcribing from the Black Book journals the draft manuscript of his Red Book, the folio-sized leather bound illuminated volume he created to contain the formal record of his journey. Jung repeatedly stated that the visions and imaginative experiences recorded in the Red Book contained the nucleus of all his later works.
Jung kept the Red Book private during his lifetime, allowing only a few of his family and associates to read from it. The only part of this visionary material that Jung chose to release in limited circulation was the Septem Sermones, which he had privately printed in 1916. Throughout his life Jung occasionally gave copies of this small book to friends and students, but it was available only as a gift from Jung himself and never offered for public sale or distribution. When Jung's biographical memoir, Memories, Dreams, Reflections, was published in 1962, the Septem Sermones ad Mortuos was included as an appendix.
