My brain bugged, and that's how my stutter began

My brain bugged, and that's how my stutter began Litteraly, anyone experienced the same? I was 9yo. I was in vacation, in a place I've always known, talking with my best friend. No stress, no traumatism (physical, psychological,...). A good child life. You know, when you touch a metallic thing and you feel like a tiny "electric shock"? I suddenly felt that in my brain. I didn't lost consciousness or anything. Just... "oh! weird. anyway." And that's how I began stuttering. This electric shock happened 3 times in my life afterwards, it didn't worsen my stutter, nor did it stop it. I never knew what happened.
