1. Stress. Significant stress can lead to migraines and I can feel them slowly start to build in the upper front of my brain above my left eye (or at least that's what it feels like). This can be stress from work or from kids or whatever.
2. Blips. I don't know how to describe these really. It's like my brain doesn't quite know how to process what's going on. An example: I gave my kids some ice cream for a snack one day after asking my wife if I should and her saying yes. 5 minutes later, she comes into the kitchen and says "Do we have any ice cream for the kids?". I respond with "Yes, I just gave them some, like we discussed." Her response: "We should give the kids some ice cream."
Now, that's a little bit of a weird conversation, and I think she was distracted by someone messaging her on her phone, but my brain just kind of "blipped" and didn't quite know how to handle it and it was instant blurred vision.
I'm convinced from some anecdotes in my life that a non-trivial amount of neurological behavior is like your blips: caused by actual qualities of the data that the brain is processing, rather than anything lower-level like chemistry and diet.
Here's an example. After some weird arguments a few years ago I began to notice how people's brains respond when they're overwhelmed by someone talking to them with an abstraction they can't easily follow.
Some people kinda 'blank out': they'll start saying 'yeah' or 'okay' in a loop, I think sort of buying time until more data comes in to see if it will make sense. Others strain themselves to follow, but become notably tired or irritable in the process. Others 'fend off' the abstraction by saying things like: 'I don't want to talk about that' or 'that sounds too complicated' . Others seem to not even register it, like they'll instantly switch the subject on a dime and seemingly not notice they did it. Others just pretend to follow even though they don't, or even just don't follow and don't pretend and just say nonsense. And I wouldn't be surprised at all if getting a migraine is another possible response that I just haven't observed/been told about yet.
It's really interesting, once you're watching out for it.
Also I need to stop saying complicated semi-incoherent shit. It seems to be bad for other people's brains.
I have also noticed this and have searched in vain trying to find a definition and/or psychological discussion about this. When I was noticing it in others I would notice myself doing it also!
The closest I got was in street hypnotists. They seek to overwhelm the target to put them in that state and then do their suggestions. The target retains the suggestions but with no awareness of hearing. They may even talk to you. The intentional manufacture of the state I think is called "induction".
But I think it mostly occurs normally between many of us at a lower level (but the hypnotists dont talk about that).
The bit I mostly interested in was what myself and others would say and why they would say it when in that non manufactured state. Imagine two people in a blip talking to each other! The other psychological definition related to the talking bit would be a type of "Freudian slip".
Your "blip" anecdote is super interesting. I know that exact sensation of disorientation (but without the migraines thankfully), and I'm curious if this has been studied in depth anywhere.
