I believe I think in words even more than average. I don't know if anyone can say how. I don't know how my brain puts together words. It's no effort for me to make a sentence; it's like they come out of a mysterious black box. But it happens all of the time, so it doesn't feel mysterious. If the black box is very central to how your brain works, it seems like the pressure of feeling and thinking, rather than erupting into images or sounds, erupts into words. Say a scary bug lands on you, and you want to swat it away. You have an immediate need to swat, and you don't think. You won't decide whether to use your right hand, or your left; you'll use your hands without thinking about it at all. Even normal actions and movements are like that, if you look; there is some small pressure with a less sudden eruption into thought or movement. So, to reiterate, that's what it seems like to me; if you miss someone, if you think in words, when the pressure builds up into a representation of your mind, it won't be a picture of the person's face, it will be words instead, "I miss Person."
