It's about a dream, an incomplete dream. There is a man in it. I can't see his face clearly, but I think it's him. I can't remember the plot in the dream. When I wake up, I have an urge to find him in reality. After working for a day, I tried to recall even more confusing episodes... This dream triggered a little bit of insights about singles, love, and life. I wanted to remember it, not just think it was a dream again, but wanted to think about it seriously, so I wrote this essay.
