Missed my flight

I had a dream I was back at school in the art rooms and I had to get something finished, when I did I put a book back and someone called Simon from uni was there. I had to run because I had a flight and before I got it I had to go back to Nottingham, then back to Bucks, then to the airport. But I'd lost track of time and only had an hour left. I was trying to run home in Bucks first, I bumped into an old friend from school and said that I had a flight in 20 minutes and I needed to call and change it, and her friend told me I couldn't. But she said I could so I was just about to call but I realised I'd already missed it. Then I woke up.
