Can someone help me with this strange dream?

My dream starts off with me and my family eating at an airport, and somehow, I know that it's in the UK, although I've never actually been there. I know we'd flown in a plane to the airport, but I don't actually remember riding in it. We ate at a restaurant called Sbarro. Everything seems to be... quiet. Not that no one was making noise. Quiet, as if... I were deaf. Later, I'd run into a girl and her parents who were complete strangers to me, and from their facial features alone I knew they were completely British. We sat down and talked, for a long time. The longer I talked with this girl and her parents, the more she seemed to resemble a - sort of - childhood crush of mine. The dream was abruptly ended here when I woke up to my phone ringing.

After answering the phone, I fell right back asleep, and even weirder, I dreamt again. Not of the same thing, but something like a continuation of the one I had. Some three days had passed and I was back in my home country, talking to my friends about how brilliant the UK was, and that I got my strange British accent for "staying in the UK for too long", then for some reason my sister decides to steal my iPhone. I don't own one, though. Problem with the first part is, in my last dream, I don't even remember going past the airport.

They say 99% of a dream is forgotten 5 minutes after a person wakes up. I still remember practically all of it. Why is this, and what does it even mean? Help, please?
