I remember, I was going to ask this a long time ago, but I don't think I ever did... As I am very interested in psychology, due to my own illness... I was wondering if this happens with anyone else?

When I get manic, or very excited, I find I have to jump up and down and clap, or do something with waving my hands to get rid of tension in my body. I just do it without thinking too much about it, but I have enough control that I only do it when I'm alone.

Does this happen with anyone else?
