My pleasure, I'm also very fond of this genre :)
If you are curious of french animation films, I just remembered "Le roi et l'oiseau". It was my favorite as a kid. And if you liked the city of lost children, it will feel familiar. Sort of the same melancholia.

I assume it will be hard to find, sadly.
There is this version on archive.org, though, if you can understand french or spanish.

With The congress and Eternal sunshine of a spotless mind, you’re in for a treat. I think Tideland checks the box as well. They are not exactly a narrative happening in another world, but the feeling of strangeness is good enough imo.
Honorable mention to the french odd ball named "la planete sauvage", though it is an animation film.
Off you go then ;)
