Collective unconscious is a term used to explain how all people are connected. Everyone has shared experiences and feelings that come from the same source, and this "source" is the collective unconscious. It is like a huge invisible library that we all have access to. It is like we all can read the same book, but the way we interpret the book is different for each person. For example, a story about a family may make you think of your own family, while it might make someone else think of their favorite TV show.
