I saw this scene from this film.
Content of scene:
Woman is dancing.
At some point, I noticed she has a tail or a tentacle and it seems to be strangling her.
Details: woman seems to be color of green, blue, or something unusual.
Torso of woman seems human, rest of her is creature-like (like a snake, maybe).
I never finished the film or saw the beginning.
Context: I saw this on cable in Los Angeles County, CA, USA, between 1985 and 1994.
Genre: possibly fantasy, or science-fiction.
Not an exact match but there is a similarly weird, (and explicit), dancing scene in Jacob’s Ladder
