This unusual strain on the brain may affect the inner ear
structures which are responsible for
equilibrium and hearing, causing normal ear pressure
to be thrown off and thus causing the clicking, squeaking, and popping noises.
Once again, I don't know much about this and am just looking for an explanation. If anyone knows more about the body's response to stress and know that this for a fact is not possible then kudos to you, but I am just throwing it out there.
