I had a dream just a few weeks ago that all the planes in the air had been hijacked by terrorists/had bombs on them, the UK was in a state of terror.
When I woke up in the morning I wasn't really sure whether it was a dream or not, only to turn on the TV and see security was being stepped up at all the airports. I nearly pooed myself.
I tend to have some awful nights sleep after a night of coding, although they're usually dreams where I'm trying to solve a problem that’s unsolvable or something bizzare.
By the way, I pick 3 :-D
