I SERIOUSLY NEED TO KNOW:

my friend showed me a pic of a galaxy type dress and it made me think of the movie i watched on a tape a couple years back…. all i can remember is that a group of people were doing a staged play in a dark theater type room i think, and at one point they were all laying down and stuff ugh i wish i had more info but i cant remember much! I know it was a play and they had weird outfits as if they were reenacting an old play or something… so lost but now its bugging me! Any ideas?
