Strange dream

I had made a strange dream in the last night. In the dream, my sister and I were in a car. The car was like a struck .Somebody was driving the car. In the car, I made a dream that there will be a car accident . And my sister would get hurt. So, I tried to change something what will happen after car accident. Because, I knew what will happen. So, I wanted to avoid the accident. I did everything for that. Then, I just waitted the event happen. When I was waitting for the resul, my sister awoke me up. So, I don't know the result. I hope I will know the result next time. Because, I dreamed that not only one time.
