I'm pretty sure that it wasn't actually Japanese, but only you think you're speaking Japanese, and can understand it because your mind is programming it to be so.

I mean, in my dreams, I've spoken gibberish once, and understood myself. Does that mean I can speak gibberish perfectly, and if someone was to come up and speak gibberish to me, I'd understand? No, ofcourse not.

If we had a recording of you all speaking Japanese in your dreams, I'm pretty certain it'd 80% be random words, and the rest would be basic words in Japanese mixed together.
