Final answer:
Celine's dream reflecting an ancient and unfamiliar religious myth aligns with Carl Jung's theories regarding the collective unconscious, where universal archetypal symbols exist and are shared culturally.
Step-by-step explanation:
Celine recently had a vivid dream that was strikingly similar to an ancient but unfamiliar religious myth. This coincidence would have been of particular interest to Carl Jung. Jung's work on the collective unconscious posited that there are archetypal symbols in dreams which are universal and shared across different cultures and locations. Jung, being one of the neo-Freudians, diverged from Freud by emphasizing the collective unconscious in addition to the personal unconscious. He believed that dreams allow us to access this collective layer of unconsciousness, wherein lies the heritage of human wisdom and symbolism that transcends personal experience.
