I recommend you to watch "This Puppeteer Is Not Normal". The plot is similar to the horror movie you described. The protagonist was faced with a world with strange elements. In the process of exploration, she found a puppeteer who performed ventriloquism. After her tongue was accidentally cut off, she began to create puppets. The plot is tight and the horror suspense is very strong. I believe you will like it very much! I hope you like this fairy's recommendation. Muah ~😗
