To put it simply whenever I try to focus/think intensely I hear these squishy popping noises, it's as if I can hear my brain clearing junk in my mind to help me focus. These noises only happen when I try to focus and they clear up once i'm in flow state, but come back when I'm knocked out of that state. Anyone know the name of this, i've had it for over 6 years i'm not sure if it's normal or not.
