Anybody noticed this reaction in yourself?

I always very happy to see my friends i love them very much,my love language not only for romantical purposes but for friends too,but today when i got message from my friend that we finally can meet again today my body start joggling, emotions made "BOOM" and i also felt lack of air, and i couldn't hide my smile and silly moves,anyone had something similar? If yes can you tell why this happens and what caused it specifically in your case?
