Dream

Q: I had done istikhaara not for myself but for a friend to see whether the person she wanted to get married to is the right one for her or not. She didn't want to do it herself as she had once tried but her emotions came in the way. On the first night I had a dream of something that was totally not related to the incident. On the second and third night I do not remember what had happned. On the fourth night I had a dream but did not remember what had happened when awakening and with no feeelings in the heart. On the fifth night I had a dream where I had seen the person I will probably marry in the future with red clothes on. I had done research where it said that when seeing red it is bad and green and white are good signs. Now does this mean that he is not right for me as I had the dream or because my intention was that I'm doing it for that girl that the person she wants to marry is not right for her. On the sixth and seventh night I did have a dream but cannot remember it.
