I used to wonder if I had some slight form of ADD or ADHD but recently I have begun to think that my specific behavior might be the inferior Se at work in me. I have frequently noticed that while I am thinking about something (without actually thinking words...?) my hands tend to be doing something weirdly tactile, like sticking and Unsticking a piece of tape or thumbing through a stack of sticky notes. The FEELING it makes in my fingers as well as the sounds are extremely pleasing to me in a half-conscious kind of way. It's repetitive and may even be loud enough to annoy people around me. At the same time, there is also usually some song or other running in my head. In the midst of ALL that, my brain is actually processing completely separate information... I guess the Ni at work?
Do any other Se inferior types experience this behavior?
