I hear what you're saying, Rambo.
I feel the same way about it.
Many of my mental images during image streaming have aspects to them that I just don't have the vocabulary to properly describe.
".. and it has a sort of thingie on the end, it's curved, and it widens as it curves, and it looks like it's hollow and it attaches to this, ummm, I don't know how to describe it ...."
And as my verbal descriptions are plodding along as slow as molasses my mental imagery just wants to zoom ahead. But then I want to stick on what I was seeing so I could describe it.
Frankly, the visual system races along at speeds that leave the verbal auditory system in the freaking dust.
I always wondered WHY? WHY is describing aloud so important? What about it is important? Putting the words to the images? Connecting the verbal to the visual? It really does hurt (it's frustrating and painful for me) to try and do this. It's extremely frustrating and has been a big impediment towards doing image streaming consistently.
I have tried an approach, however, and I don't know if is doing much good in terms of why describing the images helps, but it's this: I simply make up my own language. I make up nonsense words that describe the very things I have no words for.
So, that particular part of the door that is that frames it, you know, the part outside of the bevelling, that's an umplah. And the way it curves forward in space and expands while vibrating with colors, that's zightodling.
So, saying the umplah zightodles is much quicker, and I know what the hell I mean, even if no one else does.
Even though it's painful, though, I must admit that making yourself describe things while images streaming is a great way to improve your word choice and vocabulary, and it shows just how limited mine is in describing the various visual aspects of objects in space and how they relate and change.
However, I really feel that verbalizing can be a great impediment to the freedom of the visual intelligence. It was to shoot off at its own speed and not be crippled by a slow poke who is trying to clumsily translate everything into another system.
