This is a short story, but it took place when I was around 10-11 and I will never forget it.
First, I’ll explain the layout of my room. When you walk in the door, there is a window directly across from the door. My bed was on the wall on the right, with the headboard where the window is, so when I slept I was facing my door.
On this night, being the weird child I am, I decided to sleep the opposite way in my bed, facing the window. I slept with my cat Emma every night, with the window slightly open so Emma could sit in the windowsill and enjoy the breeze.
