What is the way to describe Calpurnia's dream in "Julius Caesar"?

In Act II, scene II of William Shakespeare's play "Julius Caesar," Calpurnia dreams that a Caesar statue was bleeding and that while smiling, Romans went to the statue and soaked their hands in the blood. She sees this as a sign that Caesar should not leave the house because there is danger facing him if he does.

Caesar refuses to believe the dream and he tells his wife that no one would ever attack him. Calpurnia tells him to make an excuse that he is sick and unable to leave the house that day. Decius tells him that if he does not go, the senators will make a mockery of him listening to his wife. Caesar decides to go.
