My lucid comeback!

This night I had some nice dreams which were all set in huge worlds, mostly it were plains but still beautifull.

1. The lands of the north

I'm some viking king or something and I live in a town somewhere on a group of large islands in the middle of a cold stormy sea. The islands are very large and mostly have plains/tundra, some large mountains and overall a cold/grey feeling which makes the town look so much more cosy... Anyway I'm leading an army to take over some lands but see this all happening by looking at an old map of the islands with each Island having a norse name.

2. The central world

I'm somewhere in a massive valley which stretches in every direction for 100 KM probably, it's mostly desert with rocks. My transportation is a small disk on wheels that can quickly (and I mean QUICKLY) traverse the rough terrain. I'm not alone though as many other people move around too, I think I even get a warning for going to fast by a knight. Then I'm at the edge where a forest begins and behind the forest lays a mighty city. But first I need to get over a large crack in the earth that's 5 meters wide and dark. There's a ramp infront of it and I go at it as fast as I can landing on the other side in one piece. I don't see a lot of the city cause I'm instantly in a house. The house has a nice interior, mediëval high class I'd say and feels warm. I meet my brother (I don't have a brother IRL) which has blond hair and mostly ignored me as he walked to his room.
