They say it marks a significant stage in learning a new language – when you begin to dream in that language. In my case, I have been studying Chinese for almost two years, with up to 4 hours a day at times. Last night, I found myself engaged in a dream conversation in which I responded to my interlocutor clearly in Chinese. Can’t remember exactly what I said, of course, but I woke up quite conscious of the fact that I had done so.
