The unconscious is so powerful that it can produce manifestations of the soul that you never consciously knew existed. It operates beneath conscious awareness.
It contains emotions, symbols, and forces that are far deeper than what the conscious mind experiences directly.
Carl Jung explored this idea extensively, particularly in The Red Book. He described a confrontation and dialogue with the unconscious, in which he encountered figures and personalities that seemed to emerge spontaneously from within his own psyche.
Jung also believed that the unconscious could sometimes manifest itself through symbolic experiences that seemed to anticipate major events. Around the period leading up to the First World War, Jung reported having disturbing visions and dreams involving blood, destruction, corpses, and Europe being devastated.
He believed that the individual psyche can sometimes participate in deeper symbolic patterns that consciousness cannot immediately understand.
