Do you think people affect each others moods?

Let’s say there’s a room full of overwhelmed people and then a calm person walks in. Do you think that the calm person helps tone down the stress of others? I know that if I’m overwhelmed and people around me are too, I feel even more overwhelmed. I walked into a room of really overwhelmed people and I was really calm. I was too tired to be overwhelmed 😂 but everyone else calmed down too.
