My biggest irrational fear is falling on the street tomorrow. One day, I was walking down a street and stumbled over a stone. Instantly, I was sucked into an invisible hole on the road. There, I found myself in a world of falling from a shallow depth. I repeated jumping into the ground beneath me. This continued until I met a professional diver. He told me, "The secret of diving into shallow space is not about doing it right. There are innumerable ways to throw your body into the air. Please enjoy the shallowness of your jumping." Without any fear, I threw my body into the shallowness. And finally, I could open my eyes and wake up. Now I enjoy throwing myself in every morning.
