I’m looking for a TV horror movie I watched around 2015 on television.
The story was about a mother who gave birth to one little girl, but another baby/twin was aborted or died before birth. The spirit of the dead unborn girl started haunting the family and eventually possessed the living daughter.
There is a scene where the possessed girl talks to her mother while being controlled by the spirit. The ghost was not really evil — she seemed sad, lonely, and wanted comfort and safety.
Near the end, the spirit in the body of her sister goes to a waterfall to kill her sister too but the mother follows her to the waterfall and convinces her not to hurt or kill the living child then the spirit leaves the girl’s body after she told the mother she is always cold at night and asks the mother to leave the window open so she can come inside and sleep with them and feel safe and warm.
In the final scene, the mother leaves the window open, and the spirit comes back into the house like air/wind.
The girl in the movie was a child, not a teenager. The movie felt more emotional and supernatural than violent. It may have been a low-budget TV movie, possibly American, Canadian, or European.
