80's sci/fantasy - Title lost and forgotten
This has been an ongoing search for 10 years now. When I ask other people about it they look at me like I'm from outerspace or something. I can only remember a short scene from movie. There is a young girl, maybe 10yr-12yr and she is in the bathroom looking up at this white old spice glass bottle in a medicine cabinet. And she reaches to grab it, but yanks her hand back after touching it as if it caused pain. And I think there was something like another dimension or something weird through the medicine cabinet. I know there were magical creatures around her after she eventually passes through and there is very thick fog that engulfs around them while in the weird dimension.
