Spaceship design from a dream

[Cognisant]

Cigar shaped ship and people walk around on the inside of the hull which creates gravity by rotating. All the machinery of the ship is along the central axis, which for the people aboard the ship is the roof of their living space. Likewise for those people windows and airlocks are in the floor, or the hull is recessed in places and the windows are angled. You can have horizontal windows on a section of the ship sticking out from the cylindrical hull. If a ship has multiple levels of living space the bedrooms will tend to be closer to the axis of rotation, where there's less gravity. Hallways and rooms tend to follow the length of the ship rather than curve around the circumferance so people looking straight see walls rather than floors curving up in front of them.

When climbing a ladder you feel pulled in the direction of rotation and the opposite when going down ladders, due to conservation of momentum. Consequently ladders are facing such that you're pulled away from the ladder when ascending and pushed into the ladder when descending. This is due to people getting lax about their ladder use and sliding down ladders, if you slide down a ladder facing the other way you could easily be flung off. The same principle applies to stairs. Elevators on very large ships tend to either be small, fast, padded booths or big slow things for moving cargo around.
