My reflection moved three seconds before I did. Nobody believes me. This morning I was brushing my teeth. My reflection raised its hand. Three seconds later, I raised mine. It happened again in the mirror. My reflection blinked before I did. It smiled before I smiled. It moved before I moved. By three seconds exactly. I called my wife. She said I'm imagining things. I recorded a video. In the footage, my reflection is always three seconds ahead. Moving. Blinking. Breathing. Everything.
