he most likely mixed reality with fantasy and created that bit as his mister hat to explore his sexuality without harming his psyche with the acknowledgement of his homosexuality, i would assume he lived near people who were very judgemental about homosexuality and his own images of gays during that era probably is the greatest obstacle for him coming out of the closet
tldr; he couldn't merge his shadow back into himself so he kept it as his "bit" which allows his homosexual desires catharsis
