I've always wondered about the role of language in dreams, and I thought that I could have some insight since my father immigrated to the US. Since his first language is Swedish, but he used English almost exclusively. I asked him a while ago what language he dreams in. He told me he didn't know! I think that thought (and dreams) should be independent of language, and this tends to lend credibility to that idea, but I would be interested to hear others insight into this.

I also have one experience I can share about bi-lingual dreaming. When I was in high school I took a trip to Germany with my German class, I stayed with a family there and spoke german a high percentage of the time. One night I dreamed in German. The wierdest thing was that my dream cue was that native German speeking people where butchering the language. So clearly I was able to dream in a different language, even though I wan't fluent enough to communicate the content of the dream, I just twisted the language to express myself.

Any similar experiences?
