Do too many different noises going on at one time, too much stimulation, and too much confusion sometimes freak any of you out?

For instance if you are in a busy store and there is a baby screaming, someone is on the intercom, someone is talking to you, everyone around you is talking to each other, there is a clanging from carts being bumped together, and you're in the cereal isle staring at the brightly colored boxes all vying for your attention do you get a little freaked out? It almost seems like everything turns to a buzzing and I'm isolated in my own little bubble and all the colors go a bit blurry.

Sometimes it doesn't need to be anything more than just too many loud noises at once. I can't seem to pick any one thing out of the mix of sounds. It is all just a garbled mess and it wasn't like this before. Sometimes it is too many bright colors and it gets me agitated. It also happens when my 5 year old is jumping up and down in front of me talking nonsense and suddenly lunges at me and puts a hand just inches from my face. That sends me for a loop. I can't describe it any better than being freaked out.

I've never mentioned it to anyone before, not even my husband, but I think he has picked up on it. He looks at me a little worried and tries to get me out of the fray or to get our little boy to back off of mommy.
