Final Scene In Movie

last scene differently years ago, compared to a recent viewing of it. I recall the same result, of the girl colliding with the truck that pulls in front of her as she's looking backwards. But I remember the visuals a bit differently. In the final scene, I recall the collision happening the same way, in slow motion with the choir-like soundtrack. But for some reason, I recall that scene to be more of a nova-like scene as though the entire car had burst into flames and the woman's features and figure, are also brightly lit, with everthing in a slow, dreamy state.

I first saw this movie back in the late 70's, so I'm probably confusing this movie with another one, but I sure seemed to remember it being this flick. Does this sound familiar to anyone?

I thought it was amazing. Right before she crashes her car I sensed that Roberto's dream was going to be a premonition about her death but couldn't figure out how it would play out. The slow motion made Nina's death sad. One of the few Argento villains, maybe the only one, that I felt sorry for.

I was always under the impression that the climatic car crash was inspired by the decapitation death of Jayne Mansfield back in 1967 which inspired Argento to film that final scene in that unusual slow-motion way.
