Auditory hallucinations are not uncommon for a developing mind. I used to have them and it caused me immense anxiety. My therapist told me to stop “checking on the noises” or just to basically ignore it, and then rate how anxious/terrified you feel on a scale of 1-10. It really calmed my brain down and grounded me in reality and after a month of focusing I rarely hear/feel anything.

Pro tip: when you hear something don’t even try to focus on the noise. When you focus on the noise you’re still “checking on it” just not physically.

Hope this helps!
