Why You Feel Watched in the Dark

Ever wake up at 2 a.m. sure someone’s there… and it’s just your jacket? You’re not broken. You’re ancient. 😁 Your brain flips to “night mode” that favors false alarms over missed threats. That means louder startles in the dark, ears that rush to “approaching,” a fast low-detail visual path that flags shapes before you can name them, and a bias to see eyes, faces, and “someone.” On a first night in a new place, one half of your brain even keeps extra watch. Light gives your threat system data, and data calms it. A sliver of lamp, a cracked curtain, even talking out loud can rewrite the story your brain is guessing.
