Yumi and the Nightmare Painter by Brandon Sanderson and Aliya Chen
She was just so hopeful. Emotions flowed inside him like blood from wounds, warm and sharp. How long had it been since he’d felt needed, wanted? He didn’t mean to lie. He wasn’t really lying, was he? Her spirits had chosen him, brought him here, perhaps to paint them. In that moment, he wanted so badly to be the hero someone needed. To have a chance to make up for the mistakes of his past. To become something. It wasn’t arrogance, as some of you might assume. It was more desperation.
Perhaps nightmares are Cultivation’s method of giving us a way of surviving trauma in a strangely safe environment. (At least safe physically.) A way to put it behind us, forget the details, but retain the growth. Nightmares are vicarious living done in our own minds.
