Must be a special effect; you're now in some sort of warehouse.  And surrounded with junk.  Lighting devices, movie props, gag jokes.  More than a little bewildered, you start to meander about.  Trick mirrors.  Trap doors.  Some leftover muppets from Jim Henson's The Labyrinth.  "Okay- what the hell am I doing here, and how the hell do I get out?" you ask aloud.  Not expecting an answer, you're startled when you hear an "I'm not sure; I'm pretty lost myself."  Whirling around, you can't decide if the three evil looking girls on the left said that, or the really tall, confused looking one on the right did.  Your guess is as good as mine.
