How do you visualize stuttering?

How do you visualize stuttering? I've always been curious how other stutterers visualize their stuttering. I liken it in my head to Stuttering Pong. There is a line of fluency and then a sound bouncing all over the place, crossing over the line every so often. I have to say the sound while it crosses for me to be fluent. However, when I've talked about it with other stutterers, I've never heard someone mention the same visualization. How does it look to you? If interested, I made a video describing what stuttering looks like to me: https://www.youtube.com/watch?v=4vlslqa1EYA
