I am having a serious dilemma

Ok so, last year I had this crush on this boy in my class, it probably lasted a few months but he ended up dating my best friend. I soon got over him and he has been dating my best friend for over a year, but a while ago I started having feelings for him again. In class we usually sit next to each other because our surnames are alphabetical so that gave us a lot of time to spend together. But once again I had gotten over this crush but I had a dream that I hooked up with my best friend. What does this mean?
