I was working with a girl on something for school. She was nice and i could see us being friends. I did not have any attraction and i even am in a relationship. for the past week she keeps appearing in my dreams. Last night it involved her being in a terrible situation and I helped her out of this situation. In my dreams she appears as an almost angelic person. i woke up with a feeling of sadness and i cannot shake it. Is there any insights on what this could symbolize?
