My stims mostly occur when I’m emotionally aroused, the most I notice stress stims and happy stims. I generally knead my hands, i.e., I open and close them repeatedly. My mood factors into this by how much I use gravity-defying behavior. So when I’m stressed I generally hold my hands down to my sides, but when it’s a happy stim I hold them up. Stressed and Happy also are different as stress causes me to completely tense up, while happy can make me be springy, almost jumping up and down. Apart from that I also do vocal stims, mostly short hums, sometimes melodic. One other sensory stimulation thing I like is blankets, so I always have a fleece blanket on the sofa, and I even have one at work.
