Boo! Don't be afraid, this is just our light blue minimal cursor for a mouse with a ghost! Ghosts are most often found in movies, TV series, books, legends, and stories, where they mean the soul of a person who didn't go to the other world. Descriptions of ghosts vary widely from an invisible presence to translucent human-like forms. Ghosts are also often seen on Halloween when young children wear a white sheet with eyes.
