All of your senses are just responses to physical stimuli that then cause chemicals to be released in your brain to create the experience of seeing, hearing, feeling etc. If similar reactions happen in the brain without external stimuli you will still perceive there to be something like hearing or seeing things that aren’t ther physically.
