I've been using my dream world as an escape from the real world but for the past few nights my dreams have been about my ex. I love him dearly and we are broken up at the moment. It's been a very painful thing for me because we still see each other frequently in class every other day. He keeps appearing in my dreams and it's nothing bad at all but when I wake up I'm sad because I know it's just a dream and the things in my dreams aren't really happening. What to do?
