This dream occurred in the early hours of the morning. It seemed to be at the end of a longer dream that I did not remember.
There is a pile of small blue cards, that look a lot like SD cards. They have some white writing on them, but I am not close enough to read them. A voice says that they are security cards. Lots of people grab the cards. The last to grab a card puts it in a computer though there does not seem to be a card reader. The computer screen, with white writing on blue, in the style of an old CRT 80 line display, switches white writing on red. RESET in 5 seconds. The countdown begins. The dream ends at a count of 2.
