I have this pet theory that LLMs are closer to how our brains generate dreams than how consciousness emerges naturally from the brain using all the other aspects you mentioned.
To me they seem like the rapid language generation bit of the brain where you say stuff without thinking about it. They are good at that but bad at thinking, remembering, visualizing and the like.
The DeepDream stuff seemed quite dreamlike (https://en.wikipedia.org/wiki/DeepDream)
