Topic: Old asian horror film. Still looking for it after a decade.
I'm looking for a very obscure film that traumatized me for life. I believe I saw it when I was about 7 or 8 years old. It was during the 80's. If anybody can offer some help then that'd be great.. I remember a couple of scenes that I'll see if I can illustrate for anybody that might be able to catch it. I have to know how scary this film actually is now. Any time I hear a ticking clock I think about this movie and it starts to freak me out when I'm alone. 
scene 1: There's a woman hiding in a car during the evening, possibly running from something. Soon she notices a hand slowly crawling up the hood of her car, very similar to "thing" from the adam's family. It proceeds to crawl up to the windshield as she slowly watches in fear, then it starts to bash the window in and when it broke through; it starts to strangle her. She passes out I think. This scene might be a prelude to scene 2, not sure.
scene 2: she ends up in the hospital in a room by herself, still knocked out. I remember a part where the camera is zoomed up really close to a wall clock that looks similar to what you see in a high school. You'd hear loud ticking sounds throughout the scene as they showed how dark the room was. Later she's visited by a husband or boyfriend and she physically fights him off and runs to the corner of the room and throws up green puke. She then looks up at him and slowly kneels down to pick up the puke and munches on it. Shortly after she is subdued by the man and possibly a nurse.
Later that night everything is calm again with that ticking sound. Then comes a big moth or butterfly tapping really loud at the window. She looked at it and was possibly mesmerized, later she sneaks out and follows this butterfly/moth as it leads her to some building. The man somehow saw her leaving and follows.
scene 3. Small birthday party or get together, she may have had a son but I don't know. Everybody had some cake, after a few bites she looked at the uneaten half on the coffee table and noticed there were maggots falling out of it.
That's all I can remember.
Any possible lead I can get to find this movie would be greatly appreciated. 
Been looking on and off for about 10 years now.. no luck so far.
