I remember that when I was searching in the internet for movies I came through a movie where I guess there was a girl who lived all alone in a big house and as far as I remember it was revealed in the end that the girl was dead herself

I can’t remember the image or poster of the movie, nor I can remember the name of the director or actors or actresses or the year when this movie was released

is it possible that is it “The Others” with Nicole Kidman?
