(Bobby is trapped in a nightmare...)
Dean Winchester: I'm telling you, all of it. Your house, your wife, it's a nightmare.
Bobby Singer: I killed her.
Dean Winchester: Bobby! This is your dream that you can wake up. I mean, hell, you can do anything.
Bobby Singer: Just leave me alone. Let her kill me already.
Dean Winchester: Look at me. You snap out of this now. You gotta snap out of this now. You're not gonna die. I'm not gonna let you die. You're like a father to me. You gotta believe me, please.
Bobby Singer: I'm dreaming?
Dean Winchester: Yes. Now take control of it.
