There are three maps located in The Natural World that show the five main areas within the dream-scape. They can be found in the southwest (x=-222279, -305093), southeast (x=267623, y=-260842) and northeast (x=240000, y=300000) corners. The map shows the location of five different areas in the dreamworld. The key to the map can be seen below.
Upon closer inspection, the map makes some sense. The Pit & Temple has a passageway to an area that has the Bright Moon Cottage. The The Natural World (where Bright Moon Cottage is located) you can see crude trees that are in a box upon linking their from Pit & Temple, meaning that Pit & Temple is hidden within the trees.
In one part in The Natural World you can see a sunken Violence District. Well, if you look, you can see a river coming from The Natural World. Which makes sense, since it is made mostly out of water. And the water flows into the dark area around Violence District, causing it to overflow and flooding it. Which could explain why The Natural World's parts of land are so elevated from the water.
But as for Happy Town and Violence District, they are on separate parts of the map. Possibly symbolizing the separation of good and evil.
