Scary Story

The door slowly opened and a person with a black ski mask and a bloody knife walked in. As I had a second to think of what was happening, I realized my flatemate must have been stabbed. So I open my sidetable draw and pulle out a fully loaded gun, then I fire three shots to their head. Meanwhile I hear my flatmate gasping for air. I ran as fast as I could to the phone. An ambulance was there within a matter of minutes. As i'm retracing what happened I realize it was just my imagination.
