Dream about a hot girl - please interpret?

[First of all, if you are wondering about the profile name, it isn't my profile.] -- In real life, I am a 16 year old male who is single. I am of Norwegian and Swedish decent, and have been thinking of going to Norway sometime within the next 5-10 years. In my dream, my family was having a Swedish family over to our house (like having a foreign exchange student, but a whole family. Dreams don't always make sense. When the family finally came, I saw the daughter of the family, who had long, wavy blonde hair, and she was the most beautiful girl ever ,whose name I belive was Katie. (Even thinking back now to what she looked like, she was incredibly good looking.) After talking at the table for a few moments getting to know them, when I got a short chance to talk to her, the family went down into our basement where they were staying to settle in. I kept waiting throughout the day for them to come upstairs to see them again, but they didn't come. After awhile, it was time for supper, and they still hadn't come up; they were still "settling in", as my mom put it in the dream. They never did come up, and I never saw her again. Then I woke up.
