When people make vector embeddings for words, it's fairly common that the embedding for one language is just a rotation of the embedding for the synonym in another language. So I think the higher level (and lower dimensional) representations of thoughts could be pretty consistent across native languages. Even though you might perceive your thoughts to be formulated in your native language, your brain almost certainly generates that representation from another, which is probably more universal. That means we could exchange these universal representations of thoughts and our own brains would do the "translation" as necessary.
