I can relate with a lot of things said here. Straying from the railroads mid conversation (even mid sentence), thinking in pictures, drawing distant associations, difficulties with transcribing thoughts, preoccupation with other things.
I struggle to find the words to express myself & it makes me feel- well, stupid. I feel like the person in my mind, isn't reflected outwardly.
If I'm given enough time, have an even temperament (this is a struggle) & the ability to write my responses, I find it much easier to form thoughts into coherent sentences.
Speak with me in person, I tend to stutter, slur words, sometimes thoughts come out backwards, & I pause frequently because I can't find the word I am looking for. After having been made fun of for it over the years, I tend to be quiet in group settings.
DAE feel this way or experience something like this?
I find it hard to stay on topic when my thoughts are in another room. They can be close to the topic, maybe tied by associative link, but they would likely to sound nonsensical to the other person.
That reminds me of "hands" and "eyes" in drawing. You see the picture in your mind but when you bring it on paper, it looks gibberish. Not at all like in your mind. The degree to which eyes are above hands can be a degree to which one views (subjective experience) personal drawing skills as poor.
When hands are above eyes, it may feel like your drawing skills are wonderful because you can draw anything you can concieve. Now, imagine both of them together. They might have equally good hands but both percieve their own skills differently.
I don't know what can I say on the topic. Embrace the chaos, maybe? I view thoughts as guests coming into my mind, guests which I didn't invite. What comes, comes. I can't force a particular guest to visit me. When I welcome all my guests, I have little trouble coming up with words.
Another analogy: Trying to squeeze a green toothpaste out of a tube with blue toothpaste. Understanding that there is no green toothpaste may help one to stop squeezing it. It's a waste of time and blue toothpaste. It's trying to be something I'm not. I might look at other people squeezing green toothpaste and think I should do the same. Maybe someone I once hold as an authority figure said that I should only squeeze out green toothpaste, or only squeeze it out in certain occasions... Ok, I think that was a sufficient explanation, but if it wasn't for you, you may ask for clarity. If you can, of course. See?
Also, sometimes I just have no idea what I'm saying. Sometimes I'm not confident in my own stance bc I'm keeping a possibility that I might be wrong on certain stuff. After all, I don't have perfect knowledge of everything. How then it's not likely that I'm wrong on something, or at least not entirely accurate?
