I'm looking for a song i heard years ago, unfortunately YouTube deletes videos like the plague so I can't find it. I remember it was from a chinese/taiwanese/hongkong movie and it was about a girl who's boyfriend dies and comes back as a ghost. She can see him and is disturbed/scared by it (not a romantic)- i think they broke up before he dies.

It's old like maybe 90s to early 2000s? I remember in one clip she's sleeping but when she turns she sees him lying next to her and she freaks out. At another point she sees him sitting in the corner or something.

The song itself was really beautiful and I can't remember it.

Know anything similar? This is from a while back so this description might not be on point, but its similar
