I think my dreams use semantic vectors that come with a tag saying they came from sensory input even though they didn't.

I am mostly monolingual but I would expect them to come with a language tag too. I believe a dream about Bob talking about cats in Spanish would directly activate your neural network like V_cats + V_spanish + V_bob_is_talking without activating the parts that would decode auditory input into that semantic vector.
