In my second LD (this afternoon taking some beauty sleep)
I met my dream mentor. I pictured him as someone looking like chuck norris, but I ended up getting a really old, friendly chinese grandmother. I knew DMs can't know things your brain doesn't know, but I wanted to test it out just to see what would happen. I asked my DM to describe the mountains of Chile in a paragraph in spanish. THEN, she actually DID.

I'm a fairly advanced spanish student, but I can't use/know all the words she used.
Now, DM's are only projections from the brain, therefore they can only know as much as your brain knows. Most likely, I picked up the words, but didn't consciously remember them, right? Is this possible, and if not, how did my dream mentor know spanish vocabulary I didn't??
