Two Different Worlds

For the past several months, Madelyn has been seeing a guy named Zane. Most nights past 9pm they'd hang out in her room or go outside. But after 6am he'd disappear... Without saying anything. Some nights he wouldn't be there at all and most days it's hard for her to remember him. As if he was a faded memory. Is Zane real? Or could he only be in her dreams?
