What does it mean having to dream of my crush wearing a t-shirt that is white in colour?

I had a crush on this guy, initially i thought he has feelings for me, but it turns he doesn't and he even rejected me. So just recently I confronted him and asked him whether does he had feelings for me, he said he never. Anyway, just after the confrontation that night i was so peaceful I had a beautiful dream - beautiful flitting beautiflies with all sizes and they are all violet in colour. Then I tried to look up in the internet for the meaning it says it means luck and transformation. Anyway two days later, even though I have forget about him, I suddenly have this dream at night where I just remembered vividly that he was wearing a white shirt. I know that the white colour certainly has to mean something, but don't really have idea what it means or implies... anyone can help? cause i tried to look into internet but still couldn't find a satisfactory answer to that.
