In last night's dream, I was preparing for some test or other similar to the SAT's. Everything was copacetic, and I was just going to bed, when the power flashed. We have all the computers backed up to some sort of battery to prevent them from shutting down, so I didn't worry about it. I went to bed and the scene skipped ahead to the next morning. My mom was looking at the computer, which had reverted to the old-fashioned monitor-and-tower setup. There was a message on the screen to the effect of, "The computer powered down unexpectedly." Her first thought was a virus, but when we explained the flash, and that it must have drained the battery, she felt better. At any rate, all our test papers were in order, and we were just about to go off to school to take the test when the dream ended.
