☐ Girl Ghost Haunting a Well

I remember seeing a movie when I was young which I am fairly sure was a Disney movie (possibly because I remember seeing the Disney logo, or perhaps just because it was on a Sunday night when Disney movies usually aired).

I remember that it was basically about a girl who had fallen down a well (which from what I remember was inside a barn) and died, and now her ghost was haunting the farm. She was harassing a boy who eventually solved her death which I guess must have set her spirit free. I remember that her ghost glowed a bright green.

It was pretty creepy and I still feel chills when I think about it. I have seen descriptions of a couple of movies that are good candidates for this movie, but have not confirmed it. What movie is it?
