pacing, and going in circles
curling my toes, or shaking/vibrating my hands or feet
tapping rhythmically, often to music
breathing to the beat of a song, so that i feel it in my chest
rubbing my face and eyes, rubbing my hands together (or even just clenching each fist so it rubs itself, inserting thumbs forcibly and popping them out)
rocking, or swinging (on a swing), or anything like that
I can't stand still without bopping my feet and kinda swaying my head, so that people often ask me what I'm dancing to. :/
and i kind of swish air and liquid in my mouth.
also, when i walk i often drag my feet so that here's a sense of friction/vibration that feels very soothing
pushing my earphones into my ear, releasing, repeating at regular intervals (while music plays)
biting my gums, grinding my teeth
knocking my knees together
flapping my hands and kinda shaking (this is reserved for special instances, like if i just finished doing something intolerable and now i'm trying not to not feel crazy anymore)
kinda closing my eyes real tight and making my eyes look all the way up into my skull
i think i stim pretty much all the time, and it's just a matter of how deliberate or intense it is, and whether it's for stress-release, or just for pleasure, or out of boredom, or just as a matter of course
