2 nights ago was the first dream i can remember that involved french. it involved curse words, strangely enough. it's about time, i studied french for 7 years and have kept it up since, for the past 7 years!
I chose other because of the way your worded your answers- you made it seem like choosing the first one meant dreaming /primarily/ in two or more languages.
I almost always dream in English, but I have experienced a couple of dreams where I was "speaking" Japanese, Spanish, French, and other languages. In the dreams, it really felt as though I was speaking those languages fluently, even though I only know a couple of words of them in real life.
Actually, I've also had dreams in which I've read books in Spanish, while conversations in the dream were in English.
But the alien dreams were cooler.
