What does it mean when you have a dream about somone you barley know?

So, I had this dream about this girl that goes to my high school. But what is weird is I was dreaming in my dream (dream within a dream) and I was dreaming about this girl and she really liked me and we were watching a movie in my basement and she picked up my arms and put them around her to cuddle, and she stopped herself and realized she made a mistake, but I said it was okay because I liked her back. So I woke up from that dream (in reality I'm still dreaming) and I thought it was interesting so I texted her and we hung out and pretty much the same thing happened, we ended up liking eachorher and everything. Then we were in the TV show Glee but that's irrevelant. So anyways, this girl I dreamed about is cute, but I never had a crush on her or anything, but I barley barley know her nor think about her. Last time I actually talked to her was during Cross Country 10 months ago. So, what do you guys think this means?
