Annabelle Loren: And you call this a party?
Frederick Loren: Could be.
Dr. David Trent: Nora, I think you're a little upset. Would you care for a sedative?
Nora Manning: Get out! Get out all of you! All of you get out and leave me alone! Just get out of here.
Frederick Loren: Pritchard, I've had enough of your spook talk.
Watson Pritchard: What's the use of saying, "Good night"?
Frederick Loren: Don't stay up thinking of ways to get rid of me, it makes wrinkles.
Chosen answer: As far as the "gliding in and out", Mrs Loren presumably uses the same body harness she used to fake her hanging. As to the rope... the film is deliberately ambiguous on whether or not the ghosts are real, as evinced by the drunk's last line in the movie; the rope trick is probably supposed to reflect this ambiguity despite being Mrs Loren's trickery.
