A bit like an episode of Dr. Who, I find myself travelling in a spaceship that is very much like a mansion. There's a downstairs, where me and most of the crew reside, and an upstairs where nobody goes. The layout reminded me of my mom and stepfather's house, only on a much larger scale and with more metal and glass.
Everyone was afraid to go upstairs, but i'm not sure why. Periodically, crew would go missing. Eventually, someone saw a strange smokey-tentacle thing come down from the rafters (yeah... rafters between upstairs and down) and snatch someone from downstairs to up. I decided to mount a rescue expedition upstairs, to find creepy mostly empty rooms with kid sized rocking chairs and clown dolls with ceramic faces. Also, zombies, which were dressed in traditional English servant costume, doing things like tidying up. Apparently, the ship needed to replenish this zombie-crew from the living crew below, and so, periodically, plucked someone up at random.
My dreams are sadly without a compelling story arc.
