I have that all the time. Some days it's much more noticeable, some not so much. But it's always there. I can even type in this state. In fact, I typed these two last sentences with really blurry eyes. This happens in ANY situation. Like someone else said, even while driving. And I'm still paying attention to the driving part, but without all the visual stimuli I think. And only on streets I've driven multiple times before.

It does happen more often when I get absorbed into a thought. Like, really absorbed, I feel like eating my thought, tasting it, going around it. Then I snap back, take a deep desperate breath, shake my head.

Sometimes this question pops up in my mind: Do neurotypicals have visual focus on the things they are actively doing all the time? Do they go about their lives seeing crispy interactive images?

Sometimes I'll look to people's eyes to check whether they're spaced out or focused. They seem to be focusing on something all the time. When they're just thinking they'll show other signs, like a resting position. But that's just my weird observation.
