For me, I will feel like there's a different quality to my surroundings, like my eyes can't focus. I will also feel "spacey" and it becomes noticeably harder to form complex thoughts. It's like I drift off mid-thought. Same for sentences: I feel like my mind blanks out and I struggle to find words for my thoughts. My brain will also feel very blank and "foggy".

I've noticed from my audio recordings that my voice will change, sometimes slightly, sometimes much more obviously depending on how spaced out I am feeling. I speak haltingly and slowly when I'm spacing out, because I'm trying to push words out with great difficulty. My voice changes as well and I sound flat, like I'm a robot.
