Why Do People Scream When They're Scared?

When someone scares you, your brain sends a quick message to your body: run or fight. Sometimes this message is so fast that your body doesn’t have time to think, it just screams! Think of screaming like a loud alarm clock that tells everyone around you that something scary has happened. This helps protect you and might even scare the thing that scared you away.
