Why did I have this bad dream?

maybe it's just ur brain caring for someone who might actually flunk out and ruin their future. maybe it's a sign that you should help him do better and set his priorities straight? you don't neccessarily have to tell him...actually, if you want to help him don't tell him, since he'll think ur just trying to help him because of some "dumb" dream. don't tell, but try and tutor him or something.
