I'm kinda similar, whenever i get really excited i have to move or else i just feel not good. Like i'll have to move my hands around, or jump around or make some weird sound. When I was little my mom always said I was going to fly away because whenever I was happy I would flap my hands so much. And then sometimes I make dog sounds. But the biggest one is the hand flapping (Because I do it the most) but I do a lot of weird things.
