What does Collitis related brain fog feel like?

Looking back on my undiagnosed years and since being in a diagnosed flare - what does collitis brain fog feel like - I always had some (and still have) where I feel off and have difficulty concentrating with symptoms such as people talking and sounding like they are the teachers from the Peanuts cartoons also difficulty concentrating and extremely drowsy with like aches and pains.

Is that it?
