When it gets dark, we can't see everything around us. Our brain thinks something might be hiding in the shadows, just like when you're in a spooky house and there's a monster behind the curtain! This makes our heart beat faster and feels like being nervous. The more unknown things there are in the dark, the more nervous we feel.
Examples
- A kid feels scared under the bed at night because they can't see what's hiding there.
- You startle when you hear a noise in the dark because your brain thinks it might be something scary.
