The basic cultural premise that work and play are a dichotomy has almost completely disintegrated, and with so much technological reliance—are day and night even the clear polarity they once were?
The term moonlighting refers to a secondary job, done in the relative secrecy granted by the light of the moon. Under the cover of night, we can become entirely different people, returning to our "ordinary" selves when the sun rises again. There is an implication that we must act a certain way during the day—more professional, conservative, “normal”—but during the night-time, we can unleash the beast. Like light and dark, we are made up of internal dualities, a Jekyll and Hyde in all of us, with the shift between identities hinging on even the most minor disguise.
Consider Clark Kent, who removes or returns his glasses to his face to transform into Superman and back again. The shift from day-mode to night-mode involves an element of costume, a quick and easy change in a phone booth or a bathroom stall on the way from the office to the club. Allow the shadows to make room for expression, evolve into your most flamboyant form. Exercise your drudgery demons on the streets of your city, transform into your own superhero, donning a pair of after-dark sunglasses, a fluffy tulle dress a chic stand-in for a cape.
