Because by most people mom wasn’t telling children fairytailes then man has a hole in consciousness already from childhood. He is missing previos primary knowledge of myths and archeotypes. Because he didnt get this knowledege in the school, his “computer” in his head simply doesn’t have that file. Then a man grows up and goes into the world.
I reccomend watching movies that can make up these sorts of imagination and realisation of spiritual world. My son Mihael got a lot of geomancy subconscious messages from movie Merlin and The Hobbit, which surpassed his linear mind. Everything works the same with adults.
