I've had a similar dream (non-LD) but with a red "haired" girl namned "Victoria Marie". Different story though, it was more like multiple scenes. She was hispanic or possibly french.

I think if you're experienced enough in LDs you can simply summon her again. I figure you should just think about her and this dream to get her again. Perhaps VILDing. Ever since I had my dream, I've been thinking about her in an attempt to have her in my dream. I've yet to have a lucid dream myself, but plenty of dreams since I discovered LDing.

As for the meaning, I'm just as stumped as you. I figure this is your "dream girl" like Courtney Mae said.

I think that these DCs are people we've seen or met or possibly some sort of combinations of different people.
