What does this dream mean?

I had a dream that people from a group i was going to join about 4 years ago where with people fromt he group i am in now. I am talking fraternities. I was going to join one about 4 or 5 years ago but it got really intense trying to get in, all of my friends dropped and i ended up dropping, i never really thought of the guys again, ever. I then went to a new school and joined a frat/group i've been in and love the guys in for 4 years or so. I had a dream where i vividly saw every person from the original group, i would have otherwise never thought of or remembered these people. they wehre at the house of the new group i am in. when i went downstairs they all turned there back to me and made remarks at me. i intern was trying to make peace, at the same time my current group of friends faded away and i was left trying to make peace with the others. I never liked these guys and thats why i quit, i have NEVER thought about it either or regretted it or anything. Why now?
