Has to be 80s/90s release. Maybe late 70s.
Only kind of remember one scene. The girl is young, with long brown hair. She walks into her parents? room and there’s a large canopy bed with white and yellow linens. She pulls a large book decorated with vines on the pages and maybe on the cover? She falls into the book and at one point her parents come into the room looking for her frantically.
