Japanese Knighthood

1. Four Mowing Vehicles

I'm in an unfamiliar city, people about, dark, maybe night. I see a map of the streets at some point because I have to go to certain places or points in the city, and have to check them all, I am clear of my intention, but other people will be dragged with me on the mission. The map shows a raster of checker board streets.
I leave on my own through town. 
I am happy that I can do something something myself, there is a subway station and other means of public transport.
Once on the road, traffic is busy, many cars, none are important. There is one big road and I get onto it though I am on foot or on a bicycle or in a very small car, but I can't really compete with the other cars, which are also faster, and I feel uncomfortable, and wonder why I am here at all. All go in the same direction, there are certain bends in the road where I can slow down or take cover, and I also hide behind the biggest truckers about, which are four mowing cars, and one is driving backward, though the seats are turned to face the driving direction. Staying behind them is the safest I can do. They are really big vehicles. This is some kind of (autosnelweg). But I get through well.
Later I am in a small house. There is something about the oldest Japanese Christian brotherhood. This is a narrow house, some steps up to get in, room is long but not much wider than the door itself. I am there when I realize I'm dreaming, other people are also here, though I thought this was for a private conference, or either a secret meeting, but a family with a kid is there, but I can tell the kid knows a lot about what happens here. It is dark inside. On the right wall are portraits and I know the history of every brotherhood and can trace them, most to recent times, but there is one of a very old European family, and they are from the Swiss Kronenburg knights, in the 1600s.
I also have questions about Ancient Greece and the first war.
In fact this place might be a jewelry smith or workplace. Somebody is dressed as SOS Piet which I think is strange, but they think it is fashionable. I can't remember the rest. This place is in the same city.
