Replying...
Intro. Someone calls you very late, when you answer you hear a male voice, you don't recognize the voice but he has a hoarse voice and seems to be unfriendly, however the voice seems to know you perfectly, in the background you hear some muffled screams, as if someone was covering the mouth of the voice in the background, you think it's a bad joke, but the voice doesn't seem to be playing games or anything like that......

Unknown call
