Making a proper investigation of the person one intends marrying

I know one should not entirely rely on dreams when taking a decision for Nikaah and rather should make mashwarah. I do respect this process, however, as sometimes Allah Ta'ala guides one through a dream in response of the istikhaara, I need to know the significance of the dream. On the 5th night, I saw the following before Fajr time begins (like 1 or 2 hours before). (I may have forgotten some other details of the dream). I saw the girl's mother. My nose was bleeding and I noticed that the front hood of my car was damaged (while in reality it has no damages), as if the car had had an accident with another car.
