An Actress Starring in Your Bad Dreams
What you need: Put on the most glamorous dress you own (maybe an old prom dress?), give your hair some Old Hollywood waves, but then go all out on the nightmare touches. Think fake blood, colored eye contacts, rotting teeth, etc.
What to say when someone asks what you are: "I don't trust nobody and nobody trusts me. I'll be the actress starring in your bad dreams."
