Though, Its rare phenomena and hasn’t happened in years now.
I used to “Blur out” sometimes where my vision turns blurry and the voices around me become muffled, and unlike spacing out, i am very aware of what’s happening around me / to me.
I usually can snap out of if i want to, by Shaking my head, but its odd because i find very draining to muster the willpower to Shaking my head, feeling very tired
When i was 6, i hit the back of my head against the side of my parents bed. I was jumping on the bed and fell and had to get stitches. Maybe that is the cause of my blurring out?


You might be describing orthostatic hypotension. Does it occur when you move after a long period of staying still?
I dont think so, but it has been years since it happened.
I hit my head a lot as a kid. I periodically experience what I assume is a form of epilepsy (no my doctor has not been any help.) It can happen at any moment, even while I am asleep. It starts very suddenly and feels surreal, like dejavu. That feeling subsides (sometimes i get flashes of dreams I have had) and is replaced by nausea, sometimes enough to make me puke. Afterwards, I tend to be mildly confused and my working memory is hindered. I have a hard time remembering what day or season it is and what the structure of my day is sposed to be. Its very annoying and I don’t believe I could get to the bottom of it without them scanning my brain while it occurs.
