>unsymbolised thinking, a trickier concept to get your head around, but essentially a thought that doesn’t manifest as words or images, but is undoubtedly present in your mind.

I've always been good at producing mental white noise (or TV static), for lack of a better term. I wonder if it's actually unsymbolised thinking. When I'm not actively thinking, there's just a massive wall of static. In these moments, I'm not thinking of nothing but I'm also not thinking of something.
