I was in a big library hiding from the librarian
This dream can have several interpretations depending on the details and emotions involved. One possible interpretation is that the dream represents a desire for knowledge or an intention to learn or grow intellectually. However, the fear of the librarian suggests that you may feel intimidated or overwhelmed by the prospect of acquiring or accessing this knowledge. You may feel that you need to hide or avoid the librarian's scrutiny to pursue your intellectual goals in your own way, or you may fear being judged or criticized for your curiosity. Alternatively, the dream may indicate a sense of guilt or shame about something you have done or neglected to do in the area of education or knowledge. You may feel that you have not lived up to your potential or that you have missed out on valuable opportunities for self-improvement. The librarian may represent your conscience or an authority figure who holds you accountable for your actions or choices. Overall, this dream suggests that you are grappling with conflicting feelings about learning and self-improvement, and that you may need to confront some underlying fears, anxieties, or regrets in order to move forward in a positive direction.
