From a scientific perspective, the world as you experience it is unambiguously made up by your brain. There's no directly experiencing the world. Only taking the electrical and chemical inputs from your sensory organs and interpreting them to create a model of what the world most likely is. It is a flawed and imperfect guess at reality based on the best available data. That is why illusions exist.
