Let's play something horror

My parents never leave me alone, but one day they had an emergency at work, so they left me alone at home. I was alone when I heard the voice of a girl coming from the restroom. I made my way to the restroom to see who was there, but there was no one, so I considered it my imagination. I called my friends and invited them over. They soon arrived, and we decided to watch a horror movie. We created the right atmosphere with blankets, pillows, and popcorn. We even turned off the lights and used the curtains. Halfway through the movie, I again heard the same screaming sound of the girl, but I ignored it again. 

We were still hungry, so we ordered pizza. Yum Yum! After devouring the cheesy goodness, we got bored, so we decided to play a game. We chose a bloody Mary. Bloody Mary. I stood in front of the mirror, holding a candle in my hand, and then I said ''Bloody Mary" three times, but nothing happened. Then it was my friend's turn, but when she said Bloody Mary, the candle blew up, and we heard a voice of a girl coming from the pantry. When we reached the scene, there was a girl with a knife! And worst of all, she was coming towards... US!

I let out a scream, but to my surprise, I only saw my parents above my face, with an annoyed expression. I guess it really was my imagination.
