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 can do that part with the eyes on purpose. It’s a bit like not actively using them anymore and they’re just in idle, not focused on anything so everything’s blurry.
Have you tried to focus on something specific instead of shaking your head?
It also happens when my attention span sinks and my thoughts become more dominant. Kind of like a warning sign that my social batteries are nearly drained.
