nightmare interpretation

Last night I had a nightmare where I was in a room with two other women, being forced to answer questions on a test that I didn't want to take. One of the women is hard to describe. I don't remember what she looked like, just that she was silent most of the time. She simply stood there in the backround. I didn't avoid her, but didn't go near her either. The other was a long haired brunette in a white dress who was stalking me as I tried to move away from her. I was scared because I didn't know the answers and I knew that my lack of knowledge was somehow going to cost me big time. When I finally refused to answer the brunette went into a rage and attacked me. Try as I might, I couldn't get away from her or even defend myself. Thats when I woke up. I have two possible interpretations. There's no doubt that the test represents my life, which has been in turmoil for months now due to my own actions. The fear I felt, as well as the inability to come up with answers is obvious. I don't know what to do to fix things. I'm pretty sure the two women both represent me in a way, but their roles are uncertain. In one version, the silent woman is my possible future, a form of redemption waiting patiently for me to figure things out on my own. The brunette is all of the bad habits and actions I'm trying to get away from, that I'm trying to change. When I refuse to keep trying to come up with answers, she overpowers me. The other version has their roles reversed. The silent woman is the me I want to change. She offers no comfort, no aid, but I am not threatened by her, because I'm already use to her. The brunette is the part of me that is nearly insane with the need for change, for improvement. She frightens me because the unknown is frightening. She stalks me because change is inevitable, it's going to happen sooner or later. When I keep resisting out of fear and uncertainty, I suffer for it. I'm leaning more towards the second version.  Either way, the meaning behind this dream is pretty clear. I'm struggling with the huge question mark that is my future and my mind is in conflict because of it. I'm scared because I don't really know what I'm doing anymore, all I do know is that I want to change.
