Rocking when at a screen
Sitting on the floor pretzel style and rocking back and forth watch the movement around me or the marbles usually with something in my hands that makes noise: shaking a bracelet in my hands, passing marbles or other small similar things or bracelet hand to hand
If standing, rocking foot to foot or pacing while snapping anything I have (pens, buttons on wallets, anything that opens and closes) or spinning keys in the air
I look at photographs of people kind of repetitively. I often find myself pacing and rocking in front of walls of pictures or posters/bulletin boards while twiddling keys or whatever other noisy thing I have on me. If I don't have something, my hands or fingers are fidgeting. It's the faces themselves and also the motion of the reflections on the glass or gloss on the photographs. I've done that since childhood. It's one of my "strongest" ones.
Reading posters or signs over and over again and/or rocking back and forth in front of them, looking from one thing or word to the next in a rhythm or pattern. I do the same with pictures on walls.
Bouncing or bobbing on the outsides of my feet when wearing shoes while biting my lower lip and squeezing a finger or fingers in one hand.
Forcefully swinging coats or jackets or other clothing across my body over and over again.
Hitting or slapping my hands on my stomach one hand then the other over and over again. Sometimes while rocking foot to foot.
Standing against a wall and bouncing my back off of it.
Rubbing my arms.
Rocking foot to foot in a backwards circle with one foot being kind of stationary.
Staring at the ground and watching the light flicker and dazzle, watching all the mulch break up into separate pieces like I can them very separate and not as just a pile of mulch.
Dangling stuff over my eyes while lying on my back.
Rubbing my face, smacking my face and forehead, legs sometimes.
Lying on my back with my legs up and crossed at the ankles and bouncing them either alone or while rubbing my face or hitting myself in some way.
Nail biting, scalp picking, face picking (I suspect this is a dermatillomania thing which is common in OCD people)
Leg bouncing.
Looking at something and crossing my eyes in a form of relaxing them (this doesn't really qualify as a stim except that I tend to look at one thing and cross, then when it feels right, look at something else and cross again).
Lying on my back and rocking back and forth while doing stuff to my face especially smashing or rubbing it with my hands and making feelings and sounds in my throat.
Rubbing feet together to go to sleep.
Rocking backwards and forwards on one foot while letting the other swing out.
The list goes on... involving noise-making, repetitive music, pacing, opening and closing drawers while foot to foot, rocking with cabinet and fridge doors while watching them and hearing them, rubbing arms and legs while sitting, pulling my arms by tucking them under my legs while sitting. Looking at glass and glass objects while rocking. This could go on and on...
