Reading about all this multilingual dreaming, I asked myself, Why isn’t anyone dreaming in English? Perhaps, I thought, people naïvely assume they dream in their native language, when in fact something else happens — perhaps it’s in recalling a dream that any language in it is identified. I myself can remember dreamtime speaking in Spanish and Mandarin, two languages I’ve studied, as well as dreamtime writing and yelling in English, my native language. But I don’t recall ever waking up and thinking, Wow, I was really fluent in English last night.
