Harry Porterie, who is like a prophet?

Professor Trelawney predicted that Harry would die, and when Sirius Black came back, it would bring him misfortune. As it turns out, I did come back. But her divination is only reliable in some cases)

She has made real predictions for Harry Potter and Voldemort (in this state, her voice is hoarse and deep), but she is crazy most of the time and likes to predict people's death (Professor Trelawney seems to have two personalities, one is calm when making correct predictions, and the other is normal madness).
