The brain uses special messengers to tell us we're scared. When something scary happens, like a loud noise or a sudden jump, your brain sends out a message using chemicals called adrenaline, which makes you feel fast and alert. It's like when you hear a big thunderclap and suddenly feel ready to run.
Examples
- A loud surprise makes your heart race like you're running from a monster.
- You see a spider on the floor and suddenly feel like you want to scream or hide.
- Your friend jumps out at you in the dark, you startle and laugh it off.
