I don’t remember the exact date or year but years ago I remember watching this Asian film on sbs. it was in colour

•A woman had a crush on a guy who didn’t reciprocate and she went to some old woman who gave her some incense. Told her to use it while she sleeps and she ends up dreaming of the guy

•Every dream she has when there’s a knock on the dream door she wakes up

•She eventually becomes really obsessed with the guy and takes a whole bunch of sleeping pills while using the incense and the last scene is of someone knocking on the dream door and her finally opening it and not waking up
