You were talking to dream about your crush which was Nightmare. And Nightmare is talking with Horror, Dust and Killer talking about you.

Dream: “here’s what to do-“

before Dream could finish, Nightmare grabbed you with one of his tentacles and brung you closer to himself

Nightmare: “mine now”

Horror: “that was a nice snatch boss”

Killer: “she’s hot…”

Dust: “shut up Killer”
