Old woman in a wheelchair and her soul emerged from her body, strange movie

It’s next very difficult question. My friend remembers a storyline about an older, white, gray-haired woman in a wheelchair (?), who was known to be dying soon. The death scene was quite strange—her soul, looking exactly like her, emerged from her body and stood next to her. The setting was either a garden or a lawn. He watched the movie on TV no later than 1998, so I’m sure this isn’t just his imagination.

Thank you in advance.
