Yes, that's exactly what I meant.
I think that what we call "communicating an idea" is really more like, say, improvising a meal. You begin with a vague notion of what you are making (e.g., a stew), but the final outcome depends on a lot of decisions that you make in response to the environment ("Hmm, we have no more chili powder, I'll use some harissa instead…"). Whereas, a lot of our language around ideas and thoughts is more like "an idea is a complete recipe".
Does that make any sense?
Another analogy is to activities like dancing or skiing...you can imagine dancing, but actual dancing is not simply a matter of executing the plan that's in your head. The entire process is an interaction with the environment.
