What are the top ten most friendliest ghosts?

The concept of "friendly ghosts" often comes from folklore, literature, and popular culture. Some of the most notable include Casper from the animated series, the Ghost of Christmas Present from Charles Dickens' "A Christmas Carol," and the playful spirits in "Ghostbusters." Other friendly apparitions include the titular ghost in "The Others," the benevolent spirits in "The Sixth Sense," and the friendly haunting in "Beetlejuice." These characters are often depicted as helpful or comforting figures rather than malevolent spirits.
