Hi Evelyn,
I know that you posted this question a while ago, but i just read it now.
I don't know for a fact that this kind of reaction is neurologically related, but i would assume that it has something to do with it, due to overstimulation.
Almost everyone i know with panic, anxiety, or bad nerves agrees that sudden noises, bright lights, etc cause uneasy feelings. Especially places like clubs, concerts, etc. My friends and i all pick the places we go based on crowds, and noise, and lights. (We're an anxious bunch though).
Anyways, just wanted you to know that you're not alone!
