Aidan Keller: I never sleep.
Rachel Keller: Then let Mommy make you something.
Evelyn: It was you! You did it.
Rachel Keller: What did I do?
Evelyn: You let the dead get in.
Evelyn: They don't dream, you know. The dead don't dream, and the dead never sleep. They wait, they watch for a way to get back.

They let the dead get in. They let the dead get in.
Aidan Keller: Mommy, I love you.
Rachel Keller: I love you too, honey, but you're not my son.
