CAN YOU HELP ME NAME THIS MOVIE?

so i watched this movie a long time ago and i remember how crazy it was and trippy and i kinda wanna try to find it online so i can watch it again. it was like a cartoon/anime movie about a girl who goes to this town with her parents or something and then like everything changes to this like trippy town with ghosts and ****. shes forced to work scrubbing the bathtubs for this place, her parents are turned into pigs, theres like this monster who keeps throwing up at one point, she meets this guy who helps her, and it ends with her leaving the place and the guy telling her to not look back... dont remember much but yeah if you can name it your a good person. sorry if this didnt make much sense im pretty high:/
