Humming, singing, rubbing my finger across my scalp and in my hair, sometimes I will catch myself randomly talking out loud... saying a word or phrase, randomly. When I was a kid I counted things, read signs, spelled things, sounded things out. I also recall jumping up and down, and some hand flapping but it was mostly out of excitement and not too often.
I think I've subconsciously tried to stop stimming and so I channeled it into singing, humming, running, and unfortunately... drinking, although I have been sober now for almost two years. I tend toward repetitive behaviors in general and have to watch myself. Sometimes I aggravate and exhaust myself with the humming and singing. My husband loves it though. Guess it's just one of those things he finds unique about me and doesn't want to change. He actually sings with me now and we make up songs, mostly about our pets and some imaginary animals - I am starting a book about the imaginary animals.
At times when I've been in severe emotional pain, I will rock back and forth.
