I'm the same way, I can shoot the stems off apples that are still in a tree but if it's neon and there's people around my brain doesn't want to balance the rifle.
I learned to balance my rifle like the sillouette shooters, and it makes all the difference at a range. I also like to sandbag my rifle and literally strap sand bags or lead to the stock to add weight for bench shooting.
It's the kind of feeling you get when you drive someone else's car or switch from a compact car to a truck, an internal imbalance, I think a lot of it has to do with your inner ear and the mechanics of muscle memory, the weights force me out of any patterns and attempting to balance the stock in a silhouette position retrain my brain to find balance again with the fluids in my inner ear. Plugs vs earmuffs might affect it too.
I like to cover my targets with a paper bag except for the bullseye and tape a cardboard paper towel tube to the bullseye sticking out, something about forcing my brain to work with impossible tunnel vision actually makes my shooting better even though I can't see my target.
I've also gotten Jimi Hendrix stuck in my head and the range noise all seemed to go with the rhythm of All along the watchtower.
My friends mom has a Vertigo illness and she looses balance in every day life and gets very sick over it and she's going through physical therapy to train her brain to not overreact to mundane everyday things that mess with the balance in her inner ear.
You might be dealing with more of a heightened sensitivity at the range, and that may just be more of a strength than a weakness if you train it.
