Welcome tom4k!
Man, that dream is beautiful. I always find it amazing when I think about how profoundly I can experience emotions in dreams during short stories. I've had a few similar dreams to the one you described and I usually felt kind of sad when I woke up, realizing that it wasn't real and that the girl didn't actually exist outside of my imagination.
I wonder if you felt similarly.

Anyway, I look forward to seeing you around and reading more of your dreams!
