And what is an angel but a ghost in drag?

We've noticed that it's back to the favorites, like a ghost, a clown or an angel.

He fills me with horror and I do not hate him. How can I hate him, Raoul? Think of Erik at my feet, in the house on the lake, underground. He accuses himself, he curses himself, he implores my forgiveness!...He confesses his cheat. He loves me! He lays at my feet an immense and tragic love. ... He has carried me off for love!...He has imprisoned me with him, underground, for love!...But he respects me: he crawls, he moans, he weeps!...And, when I stood up, Raoul, and told him that I could only despise him if he did not, then and there, give me my liberty...he offered it...he offered to show me the mysterious road...Only...only he rose too...and I was made to remember that, though he was not an angel, nor a ghost, nor a genius, he remained the voice...for he sang. And I listened ... and stayed!...That night, we did not exchange another word. He sang me to sleep.

And what is an angel
but a ghost in drag?

Work like an angel, dress like a demon, live like a ghost, and dream like a human.

He does love prophesying a misfortune, does the average British ghost. Send him out to prognosticate trouble to somebody, and he is happy. Let him force his way into a peaceful home, and turn the whole house upside down by foretelling a funeral, or predicting a bankruptcy, or hinting at a coming disgrace, or some other terrible disaster, about which nobody in their senses would want to know sooner than they could possible help, and the prior knowledge of which can serve no useful purpose whatsoever, and he feels that he is combining duty with pleasure. He would never forgive himself if anybody in his family had a trouble and he had not been there for a couple of months beforehand, doing silly tricks on the lawn or balancing himself on somebody's bedrail.
