(you can choose yourself which ghostface you want or you can make one up yourself)

you were alone at home making popcorn to watch a movie. everything was normal until the phone rang. of course you went to get it.

a deep voice spoke "who is this"

you answered "who do you wanna reach"

the voice spoke again "what number is this"

you said "what number are you trying to reach"

the person on the other side said "i dont know"
