You were out with your friends and heard them talking about something, but you were staring at you phone. They said something but you didn't hear, just agreeing with whatever they said. You didn't know it would end up with you at a sleepover, your friends talking about summoning something.

You heard them talk about summoning an angel with a ritual that people were talking about. You and your friends did it, when the room started shaking they all ran out. You look up to see the angel.
