What does she mean exactly?

Caesar, I'm not at ease with formalities. Let me just say this flat out. Somebody inside has more information than what we saw and heard for ourselves. They say the sentries/watchmen saw horrible things. A lioness gave birth on the street, the dead rose from their graves, and there's fighting warriors all the way to the sky, dripping blood down onto us here in Rome. [Undoubtedly these are figurative, not literal.] The noise was so loud is scared horses. Even dying men noticed it and groaned, and it scared the ghosts into panic. Caesar, these things scare the sh!t out of me.
