Megosztott hang

I woke up and my phone was already unlocked, showing a message I didn’t send: “Don’t go to school today.” I laughed it off… until I heard my alarm go off again from the hallway. I don’t own a second alarm. The time on my phone kept repeating the same minute over and over, like time was stuck. Then I got another message: “You already left.” I froze. My bedroom door handle started turning slowly… and I heard my own voice whisper from outside: “Open up.”
