When I went camping before, I was looking at the fire. A lot of sparks went up to the night sky. While my eyes were chasing a spark, the spark crossed a star in the night sky. I felt the sense of incompatibility at the moment. I looked at the fire and the star at the same time. Both the fire that burns in front of my eyes and the star at the far corner are forms of light that we recognize as being present in the same space and moment in time. Because the star in fact exists in a distant dimension several billion light years away, however, the light that we see it giving off is actually the glow from a remote past dating back billions of light years. Then I tried to look at not only a spark but also the collective sparks. The focus was dimmed as I was opening up my sight but I kept looking in such a condition. It was not long before the sparks and the stars crossed as if they blended with one another, thus it is hard to recognize the difference between those two. Furthermore, the sense of incongruity became stronger in my mind. The dimmed vision must be an optical illusion but I still couldn’t understand why I had felt that sense of incompatibility. I went home without resolving my doubt. Those scenes such as that the sparks cross the star, the sparks individually insist on flame, and the sparks are completely hidden by the star in the dark night are similar to the real world surrounding me somehow. That is because I usually question the significance of individual existence in a crowd and the relation between oneself and a crowd. Although I always think how I should be on any occasion, I have never found a clear answer. The scene coincided with my such reality. I may have been watching my reality through the nature of the star and the fire at that moment. The huge distance between the fire and the star reminded me to imagine time (life), which made me have a sense of the reality and then of incongruity.
