I have always been interested in stores about dream world. Because I have dream every night and they all feel super real. The inspiration of this film is from one of my own experience- I feel pain in the dream one night. What a horrible experience, it forced me to think about a question: If I have tactile sense in the dream, what's the difference between dream and reality? I don't need to have outside stimulation, my brain can produce the input, which means, I only need a brain to live. With the dream world setting, I also want to discuss the relationship between parents and child.
