ELI5: How does the brain produce dialogue, accents and other languages while dreaming? Woke up with vivid memory of speaking with a British accent. Even using slang words and phrases. Can't do this at all IRL awake... What is this black magic?

Your brain collects data from everything you see or experience while your awake. It stores this data subconsciously, and when you dream you can recall these memories. 

We also know barely anything about dreaming but it's possible that your consciousness is tapping into a pool of collective information and toying with ideas and situations you've never even considered. 

The mind is a gloriously confusing thing.
