Went out Saturday night and I'm panicking.

So, I went out Saturday night with a friend of mine. I was around a lot of people and was bombarded by their conversations and body movements. I couldn't focus on what I wanted to focus on. I'm very scared that the people around me could tell that I was paying attention to their conversations because every time they said something, I would hear their words, (word for word) and then move my body in response to their movements. I heard people to the left, people to the right and am wondering, just how close where these people to hearing me hear their conversation or tell that my body movements had anything to do with them?
