Dreaming about that you are on a campus/school is telling you that it is time to learn, study, gather information and wisdom. You are currently mainly working on your own development, competence, but also on your insecurities, doubts and obstacles that you have not yet overcome.
Learning, studying is a life process that does not stop, these kinds of dreams are a reflection of this. The question is are you the decent or the student in the process you are in? the dream reflects both and therefore asks for awareness of the fact that.
It is the right time to work on yourself in areas that arouse your interest, get an education, take a course but also consciously work on your inner self. The school/campus indicates recognition of the life lessons you are learning in real life.
