At 11pm. Another day of flu symptoms. After midday I felt like taking a nap. After sleeping for a while I drifted back to ordinary consciousness, thinking that I don't feel sleepy any more and maybe I could just get up, but then I realized that many details didn't quite match my room in real life, so I realized that instead of being awake I was having a dream of being awake. That happened twice - strange kind of feverish dreams! Eventually I woke up for real, and realized I had been sleeping for five hours.
