I have the same glitch, maybe a brain surgeon would give us writers a group discount.
I dont think it is a glitch per se, but, too many thoughts trying to cram their way into first place at once. I wish my mind was more ordered, but, it tends to just do what it wants most of the time.
Sometimes I just have to hang on for the ride, wait for the chaos to subside. Look, now its rhyming, why?
It is like an unruly roommate you cannot kick out.
Glad I am not alone in this, thanks for sharing!
