Brain clutter,

I was going a session with my neuro-divergent therapist and I mentioned brain clutter from when I talk to or interact with people, which gets stick in my brain. This brain clutter doesn't happen when I am in sessions with my therapists because the space is purely for me. So I don't take on any of there stuff. 

I was just wondering if anyone else deals with this brain clutter, like pieces of other people in your brain. I get this just from walking passed people. I usually wear sunglasses so I am protected from the sun, but when I walk passed people I have to take the sunglasses off to let the brain clutter out and its bigger when I talk with people.
