Now that you mention it, I do recall doing things like that. But I have so many things like that, across the board, all of the senses, that they don't stand out much any more. I will try to put certain colors or lights before my eyes without realizing it sometimes, try and make different sounds, sniff my food (always have to sniff the picante sauce when I open it, it's got such a sharp tangy smell), touch my face, wiggle my nose, raise my eyebrows, on and on and on. When I'm at home, anyway. I also usually am trying to even something out, a sensation, sight or smell or sound, that I got on one side of my face or body. More face than body for some reason. It bugs me if one eyes stings a little, and not the other. Air stings my eyes (it may just be California air) so that happens a lot.
Back to sound... I rub my fingers together by my ears (or sometimes not by the ears by just make the noises), and other sounds I can make with my fingers, that I know for sure. I can't think of any others now, but I will be noticing them for sure now that you've brought it up!
