Viejo bibliotecario en sueños

A librarian in a dream is the dream's image of a keeper of stored knowledge who can guide you through a body of material too large to know on your own. The librarian is not the author; the librarian knows where the relevant work is. The dream brings the librarian when you have arrived at a question in your life whose answer exists somewhere — in a tradition, a history, a body of evidence — and you need a guide to the shelves. A librarian helpful is the dream telling you the guide is available and the question is answerable. A librarian missing or hostile is the dream noting that the body of knowledge exists and the guide is not currently with you, and you will have to search the stacks yourself.
