"I don't believe you."
"What?"
"You honestly don't remember the experience."
"I would know."
"How?"
"I… I… Severus! What would someone have to gain to exposing me to dreamweaver, to creating a nightmare in my mind?"
"You can think of no one that could gain anything from trying to scare you?"
"Scare me from what exactly?"
"Me."
"WHAT!"
"Have you ever finished the nightmare, Hermione?"
"No, I don't think so. But you are one of the ones I see dying."
"Even if the nightmare was placed in your subconscious, you can still change it just like you can overpower it."
