OMG, it's incredibly, profoundly difficult to talk about this.
Here you have such a verbally unmatched phenomenon with so much of that weird colliding context and fluctuation in generic communicability that you might as well explain to a 2D entity how the third dimension works.
It is a miracle I even was able to recognize it by name when I first came across it.
In ancient times, it was said that the Persians would debate their ideas once sober and once under the influence in order to align clarity with perspective, and here you have this thing, which sees this and is like "hold my beer", fading in and out like old age, flickering the old internal lights without anyone's planned consent, and misguiding thought navigation.
I cannot speak for everyone, but there are a number of us who will tell you they don't dare write fiction (or nonfiction?) if there isn't absolutely every reason to believe they're in the safe zone, mind's eye, verbal recall, and comprehension (including that of relevance, which already has a relative nature) be damned, further complicated by the "there are different kinds" which ranks it in the realm of "phases", "moodiness", and "DID alters" (my step-step-kids each can attest experience with one of those three).
That's not brain fog. You're romanticizing a medical condition. My brain fog feels like my brain is walking through water. I know where I'm going and I know how to get there but every step on the way is slow and cumbersome and takes way more energy than it should. IDK what you are talking about. Delusional euphoria maybe.
And somehow only half of what's currently in memory gets saved on disk for later use.
I feel like I got brain fog a lot after having had COVID and being somewhat diagnosed with long covid.
Legit feels like Ive only got half the ram left and a shoddy disk that doesn't always save everything I put on it.
You then try to explain what brain fog is like with brain fog. You'd be the first person to imply it doesn't manifest differently for everyone. For me, what you said isn't at all unrelatable.
I have no idea what you are saying. Maybe the frustration of trying to communicate but not be able to find the right words in the right order are the perfect illustration of what it feels like with brain fog. Except apply it to everything and a massive headache when trying to force it. It's nothing to be romanticised. It's not something anybody would want. Drunken delirium is something entirely different.
If I come across as trying to romanticize anything, that is not my intention. I never said what I suffer from is desirable or anything, and I'm not going to start now.
