The vacant confusion and paranoia caused by a long stint at a summer festival: sleeping in the office bog, but buzzing at night; basically feeling like a fire alarm is going off in your cave when you're trying to hibernate.
I sat there staring at the log-in screen for an hour, three shaky fingers hovering above the keyboard, before I realised the extent of my fest-lag.
