im glad i wasnt the first to admit this.. i too have had a SH4 dream...
I have base board heat in my home, it typically creaks and and ticks when the pipes get hot. i was falling asleep one night, and i found myself dreaming that i was inside a command room with pipes breaking around me, and the hull making creaking noises, we were sinking! i awoke, i asked my g/f if i was talking in my sleep, she said no... thank god
