I stayed at a hotel that was having a power outage and they could not assign me a room because they couldn't tell which rooms were unoccupied. I guess the rooms themselves had some redundant power or was wired to a different grid. That night I had a dream about having room assignment logs sent to a printer. When the power went out there was a log to flip through so that there was a manual way to determine where everyone was staying in the hotel.
