A Dream Upon Waking

Maybe its the new enviornment, or the stress, or maybe I really am finally going crazy- but ever since I moved into my dorm room I've begun to have strange dreams. They're dreams that, if I had one every once in awhile it wouldn't bother me so much, but having one or two each night is beginning to concern me.
The dreams themselves are not exactly nightmares, although a great deal of them are disturbing. Most of them seem to speak to the errors of human nature via things we find as a society to be particularly horrific. The thing I think bothers me most is that when I myself am placed within the dream, I'm not doing anything. I just observe the hellish things going on around me, in comparison to other dream I will have in the same night that puts me center stage in whats going on. What does it mean when I witness terrible things but I don't seem to exist in the situation? What does it say when I am only an observer, I can't help the situation?
I'm trying to figure out if the dreams are speaking of a fear of mine- that I will only be able to observe issues, never take place in the solution, or are the dreams telling me that that outcome is already inevitable, because of the path I'm on? I've always believed in the power of dream interpretation- it helped me cope through very, very difficult times- but because I'm only able to interpret certain aspects of my dreams and only when I spend a long time thinking about it, I'm afraid that I'm not interpreting with accuracy in this case.
