Madotsuki is a former Architect. This is how she lucid dreams so easily. Masada is her former mentor and lover, who got lost in Limbo and came back wrong. Mado goes to sleep, then goes to sleep in her dream, then goes to sleep in THAT dream, and the spaceship crashes because three dream layers is too unstable. At the end, the staircase is just THERE, there is no corpse and the bell-people appear because Mado has been in Limbo all this time. This is also what's up with the spectacularly narrow apartment building. Mado does not want to leave her room because, from up here, she can pretend all the buildings aren't dilapidated broken wrecks.

Of course, this also means a happy ending. Death in Limbo means awakening.
