What exactly is this supposed to be?

Ok let me give some background info first. When I was little I was afflicted with nightmares. One dream I particularly remember involved me meeting a silver-haired girl, who was the princess of some kingdom. I couldn't tell you her name or the name of the kingdom, nor is that really important. But she was my age when I met her (like 4) and she had showed me a vision of something that was going to happen in my future. It being a long time later I don't remember what it was. But I remember that when it happened a few years later I remembered having that dream. Now about 4 and a half years ago, I had a similar dream. Same kingdom, same girl. Except I was 10 then and she was also 10. That time she showed me a vision of my grandfather falling into a pit and told me that he would die on a day that was important to me. Two years later, he died on my birthday and I recalled the dream yet again. Now last night I had another dream. But I can remember this one with a little more detail. I remember running from the government, my family and a few of my friends. We were wanted criminals. We were confronted and two of my friends were killed, but my family and I and two more of my other friends got away. We got to a canyon type thingy and all of us were captured. Each of us were held separately. One of the guards came and told me that the princess had requested an audience. So I got to where she was, she told me to sat down. She told me that it had been a while and I agreed (both of us were the same age again). She asked me how my life was and I told her. She then asked me a question, how I felt about my grandfathers death. I told her that I had been expecting it. She then asked how I felt about her being right. I told her that it was hard to believe that she was able to so accurately tell me what was going to happen to me. She told me that we were connected. I asked why I only saw her every few years. She told me that we met whenever it was possible. That is all I can recall... it probably involved me sitting in jail. But when I woke up, I wondered why instead of telling me something that was going to happen, she brought up something she had told me was going to happen at an earlier date. It feels like this is a little more than just a dream. But I have no idea what it could be. So now my questions are: who is she, and how the heck has she been able to spell out my life so accurately? The chances of something she told me actually happening in the real world must be extremely small. But what's even more insane is that she wasn't right only one time, she was right twice. The probably of that has to be mind blowingly small. Again, who is she and why does it seem like we really are connected?
