I had the same thought myself. I could be that it is anchored into the ceiling via the rotor, or more likely it is simply some AI trickery!
Yeah, I'm leaning on AI trickery as well. The chair by the window seems to be the biggest giveaway, but so are the uneven gaps between wooden slats (I don't know of any carpenter who'd allow such a travesty), never mind the obscenely low overhead above the mattress in the tail end of the thing (I think I've seen more spacious accommodations in the racks onboard a submarine).
