I similarly have a collection of numbers and phrases that I will repeat, generally in moments of stress or to ward off intrusive thoughts. I can perform these inwardly as well, though I prefer to oralize if the situation allows.
I think palilalia may fit better.
I've been reclaiming some stims/behaviors that I supressed for many, many years. They include:
Singing my thoughts out loud(terribly)
Prancing around the house on my toes.
Swinging arms around wildly.
I hit the back of my head against car seat/desk chair, not to the point of harm.
Unmasked for me means scripts are gone. I take much longer to take in and process questions, and to create responses.
