Can't help but to reiterate what you already know, that it's just a dream, and while it sucks to be reliving it every night, at least you will wake up.
If it makes you feel better, I can share my recurring nightmare which still occurs even though I am years from college. It's the day of finals and I have a horrible sinking feeling in my stomach because I forgot that I enrolled in that class and consequently didn't attend lecture all semester. And of course the class is something ridiculous like mechanical engineering with electronic components or something like that.
