Seeming to be in my current home (which is the home I grew up in as a child), yet also seeming to be in a Star Trek: The Original Show situation. I was playing the role of Uhura, yet not quite equal to the task - i.e., I was acutely aware I was supposed to be her, but wasn't her, and did not truly know her job.
I was in a room that reminded me of one specific room in this house (my brothers' former bedroom), working with a male fellow crew member (not anyone familiar from the show), attending to a fellow federation personnel who had been caught/trapped/hurt by something that happened on this ship. We seemed to be in a Star Trek 'scene', yet it was as if we were also 'playing' at it.
I had apparently been told to hail the Enterprise to request additional crew to help with this ship but I didn't really know how to operate the equipment in front of me (the first time I tried guessing at what button to press, my hail went out on the ship we were on). Chagrined, I tried another button, hoping it went out this time. I fumbled with the correct ('official', I guess) words to use. Trying to remember how she used to to things. I didn't know the name of the ship we were on. (My fellow crew member told me to call it the 'Cranberry Sauce', absolutely as if we were two children playing at Star Trek). I proceeded to o so, glancing at the dark-haired crew member trapped under something to my immediate right, wondering if he were supposed to be a Vulcan or something... "Enterprise, this is Lt. Uhura hailing from the U.S.S. Cranberry Sauce..." No reply (perhaps I still hadn't done it correctly?) before I woke up.
