I always remember being sick and dozing off while I watched movies on the couch or played video games, and not always being coherent. Or even remembering what happened afterwards. Even recently I was ill and tried to watch a movie (I don't even remember what movie now) and I was awake for about 15 minutes, and woke up a couple hours later. The TV had since been turned to a cartoon, and when I awoke and I was certain it was still the movie. It was a very confusing five minutes.
