yanagihara world

My dream the other night took place in the world of “A Little Life.” All the gang were there, but instead of four successful male friends, there were five, and in my dream, I was half-aware that I was creating the fifth character myself. I take the dream to mean: I can write like Yanagihara in my sleep. Hardly an insight—my self-belief also taunts me by day.

Does Yanagihara actually write in her sleep?
