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.

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.
