Welcome to my new fic. Okay first of all I would like to begin by saying, that this fic was originally named 'The stranger within' and had a completely different plot line altogether.

I have chosen to abandon that idea, as I just wasn't sure where to go with it. (Apologies to anyone that was reading, but the first few chapters will basically be the same with slight modification)

I have therefore decided to have this as a Hans revenge fic. When I first started writing my bitter poison fic I had intended to have Hans stay the villain all the way through, but then changed my mind so it became a Helsa fic.

This story will have Hans as villainous as they come, because IMHO it is easier to write him this way.

Anyway this takes place one year after the great thaw. Anna and Kristoff are married and Elsa is going to begin to be plagued with terrifying nightmares about Anna dying. What do they mean? well you'll have to read to find out.

Disclaimer: I do not own Disney, Frozen or the characters. I sadly only own the plot.

Chapter One.

Elsa tossed and turned and clawed at the sheets as the unwelcome, yet vivid images invaded her mind.

She found herself in a dimly lit room. The distinct smell of blood assaulted her senses, causing her to feel nauseous. A tall figure who stood menacingly in the shadows, suddenly began emitting a hideous howl as he leered over a terrified young woman. He smirked maliciously as he stroked the soft flesh to her now deathly pale cheek. Her weak, slender body had been restrained by thick chains, her mouth gagged by a filthy rag. She attempted a muffled scream as the stranger continued inflicting small, shallow cuts on her barely covered body with the sharp blade of a knife.

The young girl turned to her, tears streaming down her face. "Elsa! help me, please?"

Elsa gasped at the sound of the familiar voice. "Anna!"

Another familiar voice rang out. His tone bitter, and filled with hatred. "You're too late, Elsa. You've let your sister down. She is going to die, and it's all your fault."

"Please Hans, No!" But her pleas were drowned out by the muffled gasps and chokes of her sister's death throes as the blade slid effortlessly across the delicate throat of the young Princess.

"Anna!" Elsa bolted upright, screaming. Beads of sweat had formed on her forehead, and her hands were cold and clammy. The temperature in the room had plummeted, and a thick layer of ice now coated the walls and floor. Her heart was beating erratically and she found herself shivering and trembling, something that being an ice Queen, she never ordinarily did.

Rapid footsteps echoed outside in the hallway and the door burst open to reveal a very concerned Anna, wearing nothing but a thin nightgown. "Elsa!"

Elsa's heart slowed to a steady beat as soon she laid eyes on her sister, who thankfully looked safe and sound. "Anna?"

"I'm here, Elsa."

The young Queen's momentary despair was now replaced by slight embarrassment at the thought that her younger sister had been disturbed by one of her nightmares. "I'm sorry Anna, I didn't mean to wake you."

Anna almost slipped on the ice as she carefully made her way over to the bed. "Elsa, what happened? are you alright?"

Elsa lowered her head in shame, not daring to look her sister in the eye. Fear rose inside of her at the thought of Anna seeing how weak and pathetic she looked right now. "It's nothing."

"You're such a bad liar, Elsa. Now do you want to tell me what really happened?" she asked calmly, before bouncing onto the bed to join her older sister.

Elsa hated that her sister seemed to know her better then she knew herself. Finally she plucked up the courage to answer her. "I had...had a... nightmare."

"Oh Elsa." Anna wrapped her arms around her sister, offering whatever comfort she could.

Elsa attempted to gain composure. She felt rather silly having her sister comfort her, when it should in fact be the other way around. "Oh Anna, it was horrible."

"Do you want to talk about it?" Anna asked, as she noticed her sister's eyebrows furrowed together as if in deep concentration.

Elsa wasn't sure whether she wanted to share the details of her nightmare with Anna. At this present time, she couldn't make sense of it herself, and she didn't want to scare her baby sister. She gently shook her head. "Not really, it's probably nothing anyway."

Anna soothingly stroked her sister's platinum blonde hair. "You know, you can trust me, don't you? I won't tell anyone, not even Kristoff."

Elsa smiled, taking her sister's hand in hers. "Yes Anna, I know, but honestly, it was just a silly dream."

Anna wasn't altogether convinced it was just a silly dream, but she chose not to push it. Their relationship may have been repaired, but it was still fragile, and the young Princess was very protective of their newly-forged sisterly bond, especially after so many years apart. She didn't want anything to jeopardize it right now. "Okay Elsa, well if you need to talk, you know where I am." Anna turned to leave, until Elsa motioned for her to stop.

"Uh Anna, would you stay with me...just for tonight."

I thought she'd never ask. "Of course I will."

Elsa's face lit up. "Really?" but then she thought of Kristoff, her sister's new husband. They had only been married for one month, and here she was, stealing Anna away already. "Wait, what about Kristoff, won't he mind?"

Anna lightly chortled. "Kristoff? No way. Trust me, with him being such a heavy sleeper, he won't even know I'm missing. And I certainly won't miss his loud snoring."

Elsa stifled a giggle, before pulling the covers down and patting the mattress next to her.

Anna excitedly climbed in, before snuggling up close to her sister. "This is so nice, isn't it?"

Elsa kissed her sister's forehead. "Yeah, just like when we were kids."

Anna hugged her sister tightly. She felt surprisingly warm for a snow Queen. "Elsa, I want you to know, that no matter what, I'll always love you."

Elsa nestled her head in the crook of her sister's neck, breathing in her familiar scent. "Yeah, me too."

So I wanted to start this fic with a little sisterly bonding between Elsa and Anna, because trust me they need it.

Anyway I would like peoples thoughts.
