80's? Children's movie title
Can anyone please help me figure out the title of a children's movie I watched when I was little? My memory is very vague and I hope that the parts of the movie I remember are all actually parts from the same movie. I remember something about a little girl in her bedroom and there is another world through her mirror so she travels through her mirror into this world. There was some kind of witch type woman that did not want her there and in the end the little girl saved the "mirror world" and went back into her room through the mirror. Please, please, please help me out. This has been bugging me for so long.
Thank you!
