I guess this question is aimed towards people that have seriously studied a language for a while and are reasonably fluid with it. Do you ever find yourself dreaming in said language?
I read somewhere that the two sings that you have completely mastered a language are: catching yourself thinking in the new language without even realizing that you were doing it and dreaming in this second language, as in, speaking and interacting with people in this second language.
Is this true? I would like to know this from people that actually are fluid in several tongues, yet I know that the definition of "dreaming in a language" is probably fuzzy at best, you could dream that you were speaking say, Japanese, and the words made sense to you but you were actually just dreaming gibberish.
I would like to hear from you if you experience this, specially after prolonged and intensive sessions with the new language.
