Jung's Collective Unconscious
Carl Jung believed that there was a pool of knowledge or understandings that we as humans access on a subconscious level. He called it the "Collective Unconscious."
The theory holds that certain archetypes are remembered in the deep recesses of our mind. Jung's theory holds that our conscious mind is influenced by our subconscious whether or not we are aware of it.
In fact, sometimes the issues we experience consciously are influenced by our unconscious.
Therefore, developing a deep understanding of the cultural archetypes common to our ancient cultures and unlocking the hazy memories we have inherited can help bridge the unconscious with the conscious and lead to a more holistic view of the self and the wider world.
