Talking in a foreign language – when dreaming

Anyone else who also experienced an interesting language encounter when when dreaming?

"I'm on the back of a bus with two girls that I don't know so well. We are going down a hill and suddenly the bus driver is starting to drive faster and faster. I'm scared. Exactly when we are heading towards another steep downward slope am I standing up and shouting: "Stop the bus! We are here! It's dangerous!". The interesting part was, I shouted in Arabic.  

My conversational daily colloquial Lebanese Arabic is quite alright despite that I'm nowadays quite a lazy student. However, I was taken by great surprise waking up and remembering that I had shouted to that bus driver in a third or fourth language in my dream. I think we were in Egypt, where I lived in year 2009 (yes I practiced shouting skills in a few buses during those months...).  

It made me curious about the science of dreaming and foreign languages. I asked a Syrian friend who speaks 6 languages fluently; she said that many times the language of the conversation in her dreams are based on the language she commonly talks with to this person. According to an academic article I found (Lum & Ade 2016) this is also what research is telling:

"Language choice in bilingual dreams related to persons—most participants in the study used the same language with a dream character they used with the person the dream character represented in waking life". 

​It seems like it is not necessary of being fluent in order to dream in another language; since the subconscious mind is great of recording information. For you who are fluent in a language but can't remember dreaming in it, remember that despite being fluent in a language the brain can still have difficulty retrieving it during dreams (Sarkis 2014).
