CS prompt: Killian has a nightmare and Emma has to comfort him please

Everything he'd been working so hard on becoming was crumbling right in front of his eyes. With his heart clutched strongly in the hands of his now unreformed enemy. He stared into the vastness of pure evil and darkness held in the eyes of Rumplestiltskin. His only thought. Emma. His Emma, his one and only, and she looking up in full terror of the events unfolding. And he couldn't do anything, nothing at all and that was the worst part. She was watching his demise. It was worse than anything he could ever imagine, it was heart wrenching even without his heart being in his chest.

As the life was slowly being squeezed out of him in the most painful of ways possible, he looked down to Emma in a last attempt to seek help, anything to stop the pain. And in that second the nightmare became a dream, all the pain escaped him, filled with a sort of dread. An unknown dread.

An antagonizing scream tore the silence in the room. Then another. Louder. More painful. Whipping his head in the direction of the only sound, knowing that scream, that voice, that terror. His stomach sank in horror. His Emma crying out in pain, a pain he caused. It had transferred to her. All of his pain now emitting from Emma. How, he didn't care, all he cared about was her.

It was his fault. He'd caused this.

Running to her aid as fast as possible, but it wasn't quick enough. She collapsed onto the cold floor. The heart that now seemed linked to Emma crumpled into ash.

It was happening again.

It was Milah all over again.

And god did it frighten him.

Holding her for dear life, he could see her eyelids fluttering shut. She was almost gone.

"No…Stay awake… Emma please…" he kept begging and begging like a mantra. Slowly teardrops fell from his eyes and onto her unmoving, lifeless body, but he didn't care, all he cared about was her. Inside he was screaming. He knew how this ended. It was déjà vu.

With the little energy she had left, she lifted her head up to his face and let out a faint whisper, barley audible, while giving him one last kiss. His tears increased and everything around him was blurry. The saltiness from his tears could be tasted as he continued to kiss her; he had to keep this kiss in his memory forever.

After what seemed like seconds, her face fell backwards into his now shaking hand. She should've had longer; they should've had longer.

Tears streaming down, he couldn't help but sob. Killian cradled her lifeless head. And after a few minutes he stopped for a second and just stared at her cold body.

"I love you too"

He knew in his heart that he couldn't live without her. Ever. And so he carried on crying and sobbing and crying and sobbing for what felt like an eternity.

Suddenly he woke up, with beads of sweat running down his face, and manic breathing.

"Shhh… Don't worry, I'm here"

Looking to his left he saw his beloved.

His Emma.

Relief flooded his whole body.

She was alive.

She was still here.

"Swan… I.. I…thought…you'd…gone…"

"Hey, you could never get rid of me that easily" Emma grasped onto his still shaking hand and held it tightly, as she snuggled closer to him, telling him subconsciously that everything was going to be okay, that everything was fine.

"But…"

"I'm here and I'm not leaving anytime soon, so don't worry it was just a nightmare, it wasn't real, come here…" She then held him closer into a hug, soothing his back, as she kept reassuring him and he just listened and held her for dear life and he never wanted to let her go. Ever.

After a few minutes he spoke.

"Swan…"

"Yeah?"

"I love you so…so much." Barely a whisper but loud enough for her to hear, she just smiled in the dark and held him tighter.

"And I love you"

And this carried on, every night, the same nightmare, the same outcome for 2 weeks until finally he managed to sleep through a whole night but only if she was snuggled in the crook of his neck, close enough to hear her heartbeat.
