public speech dream

I was standing and delivering speech in front of a crowd. When I was halfway through the speech, I felt my dress (it was a brown tube dress that I wore when I graduated in the university) slipping. I was able to hold it but only when half of my brassierre was already exposed. When I looked in the crowd, I saw that the guy I liked back in college was there (back in college, I had this feeling that he liked me too but he didnt make any move to really tell me he does. I feel the same whenever we meet during gettogethers or reunion and some of my friends notice it too) together with one of his closest college buddy. I'm in a relationship with someone now but I still dream of that guy I liked in college and it really bothers me.
