What does your brain feel like?

Hey guys, so weird question but how does your brain feel like to you? I am trying to figure out whether I might have ADHD or not. I somehow can and can’t relate to what it’s like. I feel like my brain is like a highway - so much noise all the time but nothing distinctive. Like, you can hear the constant swooshing and buzzing of the cars but you can’t make out the sound of one single car if that males sense. The representation I saw so far is a bit different. More like multiple but distinctive thoughts at the same time. All at the same volume. So I‘d like to ask - how would you describe this?
