He woke up...again. Since Castiel had become human he had experienced many new things. Nightmares happened to be one of them. He woke up every time he tried to sleep. They were all about Dean. He couldn't count the times he had a nightmare about actually killing Dean. The fear on his face still makes Castiel feel terrible. Dean has long since moved on. But Cas hasn't. Every time he closes his eyes he sees Dean's face. He sees the terror. He sees the betrayal. He remembers killing all of the fake Deans as Naomi's way of testing him. He remembered when he first started. He hesitated and Naomi had to coax him through it. Then at the end he did it without any emotion. Then when it came to the real thing, he couldn't do it. He saw the real Dean begging to spare him. Asking for his Castiel. The Castiel that would never hurt Dean on purpose. The Castiel that protected Dean. The Castiel that did stuff like interrogating a cat. The Castiel that he knew and loved. It made him hurt so much. The thought of killing Dean. It made his stomach turn. What if Naomi had taken over and actually killed him? Cas couldn't stand thinking about that. What if Dean had actually died? Castiel couldn't stand the thought of that. He slowly fell asleep again. He was jerked awake not long after by the nightmares. This one Dean was begging him to stop. Begging him to find the real Castiel. And then the knife went down and Dean accepted his fate reluctantly. And Castiel killed him. He sat up in bed suddenly. His breathing was labored. He didn't know how much longer he couldn't stand this. He was going to go insane.

When he first saw Dean after the angels fell, he immediately felt safe. Dean pulled him into a tight hug. That's where Castiel felt safe. Dean had forgiven him. He felt at peace. Slowly the nightmares ceased. Every time he had one, Dean was there to wake him up and calm him down. Then one day, they stropped completely.

Castiel would never forget the look on Dean's face when he thought he was going to kill him. But he was at peace knowing Dean trusted him. He was safe and sound.
