The pictures I think in are clumsy, like unfinished comic-book panels. However, whenever I make or do something, I always know that it's not quite right because it didn't match the panel, even though the damn panel wasn't clear in the first place.
When I think I need to express something in words, I'm immediately rehearsing what words I'm going to use in my head, trying to be as precise and clear as possible. I don't know if this is a leftover habit of me typing and writing too much, or if it's just normal behavior, though.
And this says nothing of synethesia. :P
I dunno... I have a very good semantic memory but a very bad episodic memory, like the trivia is squishing out all of the stuff that people 'reminisce' about and find 'really important' (trivia is more important?). It creates a lot of funny situations like I know that something's supposed to happen at 5:30, but I only have a vague idea of what it is even though I've done it before, and forgetting to put two and two together because not only is this a tidbit of information, it applies to the real world, too. It's not enough to know that something happens at 5:30, you must also be prepared for it and go there then... which I'll forget to do because it just doesn't really seem important until about two minutes before, and then I suddenly remember that aside from being interesting trivia, it's actually going to happen.
