Maybe I’m a Figment of Your Imagination
Your world is a product of your brain. Sensory receptors in your skin and eyes send signals to your upper brain where the somatosensory and visual cortex decide involuntarily what you shall feel and see. You cannot choose not to see something when light rays enter your eyes and your cone cells convert the information into action potentials. Everything you’ve ever known is an effect which happened inside your head. How do you know it really happened? You can fit the capacity of the entire universe inside your brain, because for you, that is the only place it can possibly exist. Memory and feeling are only learned responses and ion gradients and neurotransmitters. The world is your story, and every discovery, success, and triumph is never anything but your very own.
