The glitter surrounds you until you see nothing else; some of it gets into your mouth and it tastes like sweet wine. You fall asleep, over-powered by a pleasant drowsiness...
You wake up, stark naked, in a big pile of other naked people. What the fuck is going on?
Okay, okay, just calm down and survey your environment for clues. There is a clay pitcher on a table, and white marble columns supporting the ceiling. A big pile of sheets and sandals collected in the corner. Peeled grapes.
Based on this abundance of evidence, you decide that this is ancient Rome. Ah-ha, it's so obvious! Clearly you've gone and engaged yourself in one of those decadent orgies for which those Romans were so well-known!
