I dreamt I was on a plane. This was similar to my previous plane dream in that the plane was very unlike any real plane I've ever been on.

It was as if the fuselage was closer to an egg shape than a cyllinder. The cockpit (which you could see into and through from the back end of the plane) took up just a little bit at the one, and I suppose the luggage compartment was underneath. The passenger compartment took up the rest of the egg, and so was this very large and open, but dark, space, subdivided approximately vertically, at least on the sides, by wide steps, such that some passengers sat below the steps, maybe in proper seats, and everybody above the steps just sat on the floor, usually in the middle of a next made by their own luggage. High above that was the roof of the plane, undecorated by interior wall coverings, luggage racks, or even lights, hence it being pretty dark inside.

My personal tradition was to sit at the very middle/back of this upper compartment, because then I could stretch out with my back against the wall. But on this plane the back wall was broken. There were some straps loosely keeping things together, but beyond that was just the sky. So I was sitting a little farther away this time, trying to think if I could strap my luggage together and anchor it to the walls to the sides of the opening in order to make myself a luggage nest that I could feel a bit more secure in. Things stayed surprisingly in place on the floor, even during takeoff and turns, but I didn't trust friction between my luggage and the floor enough to rely on it for purposes of not falling out of the plane.

Later in the dream I found myself trying to find a spot on the steps. This might be a little less precarious than by the back of the plane, since at worst you might fall into the middle opening down into the lower passenger compartment.
