I am always either at an airport about to fly somewhere, or I am travelling to a station to take a train somewhere. Everything is under control, then things start to go wrong. If I am getting the train, maybe I get off the connecting train at the wrong stop. Or if I am walking to the station I get distracted by something. If it's the airport, it seems to be delays through security, or I go to the wrong terminal.
It always ends up with me panicking and running for the train or the plane on the last minute despite having given myself plenty of time initially. But I never know if I make it or not, I always wake up.
