Does anyone know what movie this is?

I watched a movie years ago and there’s only a few things I remember about it. I remember a teenage girl had asthma and she fell to the floor and tried to reach for her inhaler but a woman stepped on it breaking it.

I remember after the woman broke it she said “how clumsy of me”. There was also a ghost girl who brought the girl with Asthma back to life. At the end the ghost girl said to the woman who broke the girls inhaler “why did you push me?” And the next thing I remember was the women accidentally falling out of a window to her death.

At the beginning this woman was pretending to be a ghost in what I think was meant to be a haunted house but I’m really not sure.

Does thing ring a bell to anyone? Can anyone help at all?
