The famous psychoanalyst Donald Winnicott came up with the term Transitional Object. His idea had to do with things that symbolically connect with Mom during the process of independence and separation.
Since then the term has expanded to encompass a larger territory. We all understand that humans live in conflict between safety and comfort, and adventure and newness. Winnicott, in his psychoanalytic way, connected it all to connection with Mother but it goes beyond that.
Things and ideas that connect us with our past (which includes our orienting culture in general) are meaningful to those who have strong attachments.
Jordan Peterson often speaks of the importance of the instinctive "orienting reflex" in animals and humans. We all observe how much people vary in their fearfulness and adventurousness. You could view adventurousness as a way of creating excitement by becoming somewhat disoriented, away from safe, familiar, and orienting things, places, and people.
Then for most people, the somewhat disorienting adventure is finished with a return to the things and symbols which signify, or actually are, safe, comfortable, and familiar. Adults do what little kids do.
