Carl Jung, a founding father of psychology and a one time protégé of Sigmund Freud was renowned for his self-exploration, in particular study of his own dreams. One of Jung’s first vivid dreams caused him so much distress he believed he was becoming psychotic.
Jung told of a dream he had one night in the early part of 1913. In this dream Jung saw a “monstrous flood”. He also related that in the dream he saw literally thousands of people dying and civilisation breaking down. Further to this, the flooding waters turned into blood. This dream would persist in Jung’s subconscious for many weeks and he believed sincerely that he might be going insane.
