It actually happened to a friend of mine! We were in the same friend group, where 2 people had a stutter (including me). And she started to stutter as well sometimes. But we had a chat about it and she noticed that she was able to snap out of it by her will power. Maybe it’s insane to think, but I feel it was helpful that we noticed it on time, when she wasn’t deep into stuttering mindset yet 😅 wild how it works
