About 15 yars ago I was deeply involved in some control software running on a PDP-11. It was a safety system for railroads, and the work was so intense I started dreaming about it. One recurring dream I still remember to this day: I was working on my own brain, and I'd messed up the device driver for my eyelids. I couldn't open them. And of course that meant I couldn't fix the software because I couldn't open my eyes to see it.
