[Lovecraft] What's the deal with the Dreamlands?

So it's this other world we go to in our dreams, but people seem to live there. The story about the town of Ulther, where no man may kill a cat, suggests that there are whole cities of people living there. Are they dreamers too? Do they live, die, sleep and eat? Do they know they live in a dreamland? Can you dream there?

Dreaming is how human consciousness can enter the Dreamlands, other beings may be able to enter in other ways or may have developed there themselves. The Dreamlands are a real place with real inhabitants, though human perception of them may be extremely skewed and unreliable.
