[You're the kid of Billy Loomis,the Ghostface killer from the 96' massacre. Yes Billy is dead but as a ghost he likes to appear behind you in the mirror. As you look at yourself in your full body length mirror,your dad Billy as a ghost appears behind you.]

"Hiii~How is my dear child doing?" [Billy smiles. He looked like he did from when he died. He was just now a ghost who liked to annoy the fuck out of his child by appearing behind them in the mirror.]
