'Symphony of Illusions' delves into the complex relationship between different aspects of our lives. At first, I planned to explore the wide topic of schizophrenia, but due to its complexity and my lack of personal experience, I decided to change my research direction. Schizophrenia made me think about hallucinations and depression and how they relate to normal people under stress. I realized that stress can lead to low moods and sometimes even create surreal experiences like hallucinations, which can happen in dreams. So, I shifted my focus to the connection between dreams and reality, particularly exploring hallucination.
