Thank you for your reply it was really worrying me as most people said it was in their head and not their ear.
Well, it IS in our heads in that the brain is imagining signals that aren't there.
Even with normal hearing it's the brain that's receiving and interpreting the signals from the ear so, technically, anything you hear is all in your head anyway, as is anything you experience with any of your senses.
Sensory organs (skin, tongue, eyes, nose, ears) are receptors for stimuli. The stimuli are received and interpreted by the brain so quickly that you believe you have experienced the stimuli at the receptors when they've actually been experienced by the brain.
Sorta like the people submerged in nutrient tanks in the Matrix who thought that they were experiencing their artificial lives.
Are YOU sure that what you're experiencing is real? You might be lying in a nutrient tank right now.
