I do - it’s extremely trippy that it’s even possible. However, I will say that it’s more rare and it happens in just general thought, but definitely more when I hyperfixate on it like you mention above. Try to not fixate on it too much possibly, the anxiety may be causing increased stutter, but unsure really. Although I could see this method as a way to cope with what it might feel like and then then be kind to yourself following it.
