In William Shakespeare's play "Julius Caesar," Caesar's wife, Calpurnia, begs him to stay home because she dreamed of his murder. At this point in the play, Act 2, Scene 2, Brutus and other Roman senators have decided to murder Caesar when he comes to the Capitol.
The day after Brutus takes an oath to kill Caesar in the best interests of Rome, Calpurnia dreams of Caesar's statue spouting blood in a fountain in which Romans wash their hands. She interprets the dream as foretelling Caesar's murder. She also tells Caesar about portents she's heard, such as a lioness giving birth in the streets and the dead escaping their graves. Although Caesar responds by saying these events could be bad omens for anyone, not necessarily him, he does have priests sacrifice an animal to forecast the future and determine the meaning of his wife's dream.
A short while later, he learns that the priests found no heart in the sacrificial animal. They urge him not to go to the Capitol. When Decius, who is secretly conspiring with Brutus to kill Caesar, arrives to accompany Caesar to the Capitol, Caesar at first says he won't go and tells Decius about Calpurnia's dream. Decius says that the dream is a good omen, showing that Rome draws its life blood from Caesar and that the senators might mock Caesar for succumbing to his wife's fears. Not wanting to be mocked, Caesar leaves with Decius for the Capitol, where Brutus and the other conspirators stab him to death.
