The Unburdening (1983)

In this surreal, overstated, black-and-white film by Marcel Schuepbach, a young woman is slowly driven to near insanity by an inner desire for a passionate existence, while she lives a dull life at her grandmother's country home. The grandmother recalls how her own daughter lost hold of sanity and died on her lover's grave -- and she begins to see similarities in her granddaughter's behavior.

Unfortunately the movie The Unburdening is not yet available on Disney Plus.
