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?


I get like that when my blood pressure drops very low, but I have abnormally low blood pressure unless I take insane amounts of salt to counterbalance that.
Next time it happens, try tensing your abs. That will raise your blood pressure, and if it counteracts your blurring out, then it might be a blood pressure issue, instead of some sort of traumatic brain injury, like you’re afraid of.
Same. I was morbidly obese and on several blood pressure meds to lower my blood pressure. As shed the weight and got fit, my blood pressure meds were too much, and I would get that blurred feeling, especially if stood up quickly.
The standing up thing is called orthostatic hypotension, and flexing your quads is a bit more effective than your abs to fix it.
I don’t get the standing up too fast “blackout” a lot , just sometimes. We always called it a freebie. I thought it was normal.
