A film including seeing either no reflection or a skeleton's reflection

Hi, I can’t remember the name of a film I saw as a little child, which means I can remember neither any actors nor any detailed plot but it must’ve been made in the 80s or 90s.

One thing I remember, which made me afraid of darkness, is that it included a scene in which a person looked into a mirror and saw either no reflection or their skeleton’s reflection. I’m not sure which one but I’m sure there was a skeleton/skull at some point in the film.

I’m entirely not sure but it was probably set in between Victorian times and present, like a retrospect of some sort.
