I was in the Star Wars universe. I may have been a handmaiden for Padme (or some other queen, because the emperor was already in charge). We were separated by colors; the body guard handmaidens were in blue. I was in green. I don't know the significance.
Anyway, we were captured by the Empire along with a bunch of other young people (teens and early twenties). They separated us into groups and told us we were going to face something. There were five rooms, each with a different thing that might kill us. If we survived... I don't know. We were part of the Empire or something. If we didn't, we were going to be transported to another universe to a place called New York where, upon arrival, we would probably be immediately killed by a man with a shield.
My group was "preparing", trying to figure out what we would do. Another group was in a room and there was poising and lots of screaming and dying. For some reason, one of the girls in that group kept coming to give us things like shirts and stuff. I was suspicious of her and suspected the shirts were poison. Finally, most of the group was killed and the rest of the (very injured) survivors were transported off. My group was transported to our room, where there was a giant tree with tentacles that plunged down into a base of goo. We were put into the goo. Everyone sort of flailed around, fighting and trying to defend ourselves. I hid and tried to figure out how to defeat it. I finally figured out we needed to attack it from three angles all at once. I tried to explain, but since I was the smallest and weakest, they didn't want to listen to me. Finally we started.
I don't know how the dream ended. In the dream, I was somehow related to the Emperor, which didn't give me any advantage, had powers (not necessarily the Force). I think Darth Vader may have been a woman.
