Controlled Hallucination of Perceptual Experience

Perceptual experiences are a controlled hallucination by the brain, based on prediction errors between expectation and sensory input. The brain constructs the perceptual content based on sensory signals, creating an active interpretation of the world that is calibrated by external stimuli. While our experiences are not arbitrary, they are always a construction influenced by sensory signals from the world, ensuring they align with our behavior. Color, for instance, is a creation of the brain from colorless electromagnetic radiation, illustrating how our experiences are not a direct reflection of the external world.
