I have an internal monologue. It's a bit like a narrator in my head, narrating my thoughts.

I think - and this is highly speculative on my part - that it's a sign of thinking mainly with the part of the brain that handles language. Whenever I take one of those questionnaires designed to tell whether I use mainly the left or right side of my brain, I land very heavily on the left side - analytical, linguistic, mathematical. I can use the other side if I want to; but I find it surprisingly easy to become almost a caricature of a left-brain thinker.

My internal monologue quite probably restricts me to (mainly) ideas that are easily expressed in English. Up until now, I could see this as a weakness, but I couldn't see any easy way around it. (One advantage of the internal monologue, on the other hand, is that I usually find it easy to speak my thoughts out loud; because they're already in word form)

But now, you tell me that you don't seem to have an internal monologue. Does this mean that you can easily think of things that are not easily expressed in English?
