There is some sort of an annoying vibration kind of like a low level hum that seems to be located just on the other side of the head of my bed, where my pillow rests against the inner wall of the spaceship. I am used to the inner wall being cold and sometimes even a bit sweaty from condensation (I have to keep reminding myself that there are no windows in here and that all of the air, moisture and just about every secretion of mine, not to mention the aliens, gets recycled and recirculated) but this vibrating sound/noise is new, and therefore captures my attention. I have to admit I am slightly worried about the sound/noise but have confidence that if anything is wrong, first of all, that they will know about it, and secondly, that they will repair it immediately, as the integrity of this ship is essential to their survival as well as my own.
