Oh yeah! I have had that phenomena pop up on occasion. Didn't know it was a thing.

It isn't a result of repetition for me though. Since I have practiced meditation enough, I can watch how my consciousness shifts and changes. I remember watching a creeping doubt enter, and then a word loses meaning, or I'd forget how it is spelled, even while staring at it. Knowing that jusf a few seconds ago, I knew what it was. I also chalk it up as a state change. I sometimes google it just to be sure and if it shows up, let it go and move on. I don't remember if I ever tried sitting through and seeing how the consciousness shifts back -- would be interesting to watch what happens.
