Dream and Lisbeth
"Dream," she repeated. She tilted her head slightly, taking in that information. If she had been anywhere but Madison Valley, she would have just taken the man's name at face value -- after all, she occasionally went by Wasp. She spoke to someone who went by Plague. However, this was a completely different world than hers.
"Do you dream, then?" she asked, curious. "I don't." Then, after a moment's consideration. "I do, but they're horrible, so I block them out."
If this man was actually Dream, she figured he'd already know that. Or else she wouldn't be as open about not liking it when she dreamed.
