Mirror, Mirror On the Wall
I was working on a computer, on a dresser with a mirror behind it. As I was working, I looked in the mirror and what I saw made my blood run cold. I caught my reflection in my peripheral vision not doing what I was doing. The second I focused on it, it snapped back. I know how mirrors work, but I also “know” that I saw something weird.
