I woke up, slowly opened my eyes, and wanted to get up. Suddenly my mind went blank. It seemed like only a while, and it seemed like a long time. The sound of my husband playing games, typing on the keyboard and clicking the mouse could still be heard in my ears, but why were there so many pictures in my mind? Familiar and unfamiliar faces appear across each other. Although they are not familiar to each other, they know their names, backgrounds, words, and deeds. Why are they so familiar? They shouldn't be from the same generation, so why do they appear in my mind at the same time?
