Return to Oz (1985)

Dorothy Gale has recently come home from the Land of Oz and is now almost back to perfect health since the incident of the tornado, but she can't get that wonderful place out of her head. She frequently talks about it and can't get any sleep at night. Aunt Em worries about her health/well-being. Thinking that she is suffering from delusional depression and acute insomnia, she decides to take her to see a special doctor in another town. While he tries to treat her with electroshock treatment and take those nasty dreams away from her head, she is rescued by a mysterious girl who leads her back to Oz for a new adventure.
