It was nighttime, and my family was driving down the road. I looked up at the road signs, and something immediately felt wrong. The signs weren't lighting up from the car's headlights like they normally do, even though everything else around them was illuminated.
It was almost as if the headlights were shining past the signs instead of reflecting off them.
Then, in a single instant, everything snapped back to normal. The signs suddenly lit up exactly the way they were supposed to, with no gradual change at all. It looked like a video game was loading textures or lighting or something. Now this is extremely scary so like if any of you know what that could possibly be or if it like a brain illusion or something, please let me know
