Always the same but only vaguely familiar...

Lately, every dream had been the same. A winding street, people running up it in alarm. Karina was young, pushing her baby sister in a pram. Her heart begins to pound as she runs towards the commotion. A house, hers?, is ablaze. She screams and races towards it, theres something precious to her in there, people? There is so much smoke, the ceiling is caving in and cinders form the raging fire keep burning her eyes and bare legs. She trying to scream but shes choking and coughing. A boy is yelling and wrapping his jacket around her, triyng to pull her with him but she's struggling and crying, begging him to let her search the house; he is burning too. She is dragged out, the house collapses and she is distraught and shaking. The air is so full of ash. Who did this..? Her sister; where is her sister? Safe. The boy, she is sure she knows him. She thumps her fist on his chest and then buries her head into the crook of his neck and cries.
Next the boy is older, hes holding her in a loving embrace, they're in a huge room with marble pillars and a polished floor. Suddenly the floor splits open and the room starts crumbling. She falls down into a dark pit, the bottom is filled with thick blood. The boy is reaching for her and pulling her up onto a ledge. He cups her head in his hands and kisses her as though for one last time and tells her "everytihng will be ok, i've made sure of that I promise. I love you Karina." A claw rises from the blood and pierces his body and pulls him into the pool of blood. She jumps down and frantically searches for him but cant find him. Everytihng around her disappears and she is left clutching dead desert earth and broken glass. She screams and pulls at her hair.

She jolts awake, panting for breath and sweaitng slightly, cupping her head in her hands and wiping away the tears she's been crying. She looks around in the dark but doesnt recognise the room at first. She slides out of the bed and looks in the mirror on the wall; she doesnt want to forget what she looks like. A few scars, how did she get them..? Dark circles under her eyes, has she not been sleeping lately?
A note is pinned to the mirror and reads: 'you are somewhere safe, you live in this house, your love left it to you. You are 25. Your sister Katrin is in the room directly across the hall.'
Karina sits down on the bed and lets her surroundings sink in and makes inferrences form the note. 1) She is used to being in danger from something. 2) The past few years were a blur because she didnt know how old she was. 3) The man she loved is now most probably dead, and the boy from her dream 4) She has money to survive on 5) Her sister is safe too.

She wants to leave this place for a while. She feels slightly suffocated and boxed in even though the house is huge. She looks under her pillow and finds a wand with her initials carved into it and taps it on her knee. She wonders what it would be like to be around wizards; she doesnt think she ever has been properly. Maybe she could go out and change somebody's life. Maybe she could find someone like her.
A few memories gradually begin to return as the sun rises outside her window and stretches across the bed. She and her sister have been living like muggles, but have been hiding from them too. Some muggles have been cruel to them. A change of scenery with their own kind might be beneficial. She creeps across the hall and looks in to see a girl sleeping soundly in her bed. She barely recognises her to be her sister if it werent for the teddy bear that Karina recognised from her dreams that had once been hers.
"Its time for a change sis, don't worry," She whispers. "We'll be ok..."
