I remember seeing a movie as a young child 8 or 10 years old. It is not a children's movie.

There is a scene in the movie where there is a mirror on the upper floor of a large house/mansion in the corner of the room. The girl or woman sees the mirror, and a drop of blood forms in the center and the drop trails down the surface.

The girl or woman goes into the mirror somehow and ends up in a fantasy world with goblins.

That is all I remember. It had to come out before year 2000.

I'm not sure about the mirror with blood but you might check Labyrinth (David Bowie, Jennifer Connelly)? Labyrinth (1986) - IMDb (http://www.imdb.com/title/tt0091369/?ref_=sr_2)
