Dreaming of experiencing fear and anxiety can be a reflection of your current state of mind. It may indicate that you are feeling overwhelmed and stressed in your waking life. The fact that you were carrying a lot of books in your dream could symbolize a heavy mental load or responsibilities that you are carrying. This could be related to work, school, or personal matters. The fear and anxiety you felt in the dream may be a manifestation of your subconscious mind trying to process and cope with these stressors. It is important to take a step back and evaluate your current situation. Are you taking on too much? Are there ways to lighten your load? It may also be helpful to find healthy ways to manage your stress and anxiety, such as exercise, meditation, or talking to a trusted friend or therapist. By addressing these underlying issues, you may find relief from the fear and anxiety that is plaguing you in your dreams.
