Stimming?

It doesn't happen all that often, as I think my normal state is one of mild depression, but when I am very happy, my wife says that I become very irritating; so maybe I do become rather bouncy and demonstrative.

I don't know which it is, but if something is exciting, I bounce, clap and make a high-pitched "eeeeee!" noise. The problem with this is that I find quite a lot of things exciting, so this happens quite a lot!

No you’re not being strange,. Excitement can be shown in multiple levels 

lol try this. System of a down - bounce

its a song
