we have one of those old light switches in the hallway and others in the house will sometimes flick it on/off and if my door is even a little bit open.. it's so loud it's almost like someone slapping me on the back of the neck with a metal ruler... and sometimes I react to it like I have been.. and yes I am a musician, my first guitar back in 1970 was an electric and I have had one ever since.

I also have rather acute vertigo
