What causes auditory hallucinations in the brain? For example, when you are sleep deprived, it is possible to hear things very clearly as if they were real. For example, voices of people talking, which some people with schizophrenia experience commonly in their daily lives. But of course there is no input from the ears. So what exactly is happening and how is that possible?

Think about it that way: everything youre aware of, literally everything, does not exist in the way you think it does. Youre brain creates everything you see, hear, feel… Colours and sound dont exist in youre brain or in the world. They only appear in youre consciousness. Your whole awareness is a hallucination. Thats why you dream. Youre brain can completely create your experience.
So it also can create sound that dont come from waves of air. Sound is not really sound. Its pressure in the air, your brain picks it up and create a sound out of it.
