So ever since I was 15, I've noticed that my brain counts stuff.
It's hard to explain, I don't do it consciously.
I count surfaces with my fingers from afar.
So say right now I'm looking at my walk and I see wall / curtain /wall / curtain / wall. My brain will count the different surfaces automatically. It's not conscious. I think my fingers slightly move when I do it. It's always 5. So starts with wall little finger/ curtain ring finger/ wall middle finger/ curtain second finger and wall again / thumb.
My brain is basically always trying to scan the room or whatever it is for surfaces which fit into that order of my fingers - so 5. It's super random and I hadn't thought about it consciously in ages, but I do it a lot.
Now I'm looking at the wall opposite and counted door/ wall / TV / wall/ door.
Does anyone else do something similar ?
