Hello! This is my first Dr Who fanfic. I was inspired by the fact that Steven Moffat uses the everyday and twists them into terrifying monsters or different realities.

I wanted to do something like that; there is one thing he's not done yet that no-one can avoid. So I'm going to pinch the idea before he can, hee hee...

Disclaimer: I don't own Dr Who. I want a TARDIS though as it means I can lie in in the mornings and still get to school in time for my exams. Sigh...

Tammy slowly rubbed the conditioner into her hair, feeling the soap bubbles rising beneath her fingers. She brushed the escaping soapy mixture away from her eyes before thrusting her head back under the hot shower. She let the cascade of water wash her worries away, her worries about school, exams, parents; everything was lost under the tumble of relaxing heat. Well... almost every worry…

Tammy shook her head to remove that memory. That was a one-off. It hadn't happened since…

She turned her head to look sideways at the wide mirror stretching across the opposite wall. Her reflection stared back, her blue eyes blinking away the water running down her face. Tammy experimentally rubbed her nose. The Tammy beyond the mirror copied her. Tammy flicked her darkened hair away from her face and the other Tammy did also. Tammy wiped the conditioner out of her ears and ran her hands through her hair; everything back to normal then. She cast a sidelong glance at the mirror. She caught her own eye and looked away.

Tammy cast her mind back to the day before. Had it been a trick of the eye? Or had she really seen what she had seen?

She thought about being in her bedroom. Surely not; it was an inanimate object. It wasn't alive…

That was enough for her. She turned the shower off after checking her hair one last time and clambered out of the shower, rapping her blue towel around her. She rubbed her hair and body dry before dressing in her pyjamas. Tammy carried her clothes back to her room opposite the bathroom. She dumped them on her bed and stood in front of her mirror. Her damp hair was starting to irritate her so she pulled it back from her pale face in a ponytail. Then something on her drawers caught her eye.

Slowly, she approached her chest of drawers and picked up her crystal from the top.

The crystal was a pale cylinder of white meteorite rock. At least, that was what the lady at the market stall had said. Tammy had bought the crystal for £5 – a bargain the woman had said. Apparently the meteorite had fallen in the woman's garden and she had used the rock she had found in the centre. Tammy didn't really care. There was something about the crystal that fascinated her.

There was a giggle and something red flashed in the corner of Tammy's eye; Tammy swung round. There was no-one in her room. Her breathing increased slowly as Tammy started to panic. She was seeing things yesterday; now she was hearing things…

There it was again, a faint giggle. Tammy slowly turned her head towards her mirror. She remembered yesterday about how her reflection had been too slow at following her blinking. Tammy's reflection was now facing her, her arms folded over her chest. Tammy's hand clenched over the crystal and she dropped her hands. Her reflection just smiled.

Tammy's breathing was now jagged and sharp. She watched herself, her eyes wide. She knew that if she just moved out of the mirror's view, this nightmare will stop. It had yesterday. But Tammy couldn't bring herself to take the step she needed. The other Tammy's eyes flicked down her body and rested on her right hand. Tammy slowly pulled her attention from herself and looked down. The crystal was glowing; flickering white light was spewing from within.

As soon as her attention was away from the mirror, the other Tammy's eyes flicked up. They were alight with a dark flame and her grin was wide. The other Tammy unclenched her arms and, in one swift movement, threw herself through the mirror.

From downstairs, Tammy's mother heard a short scream and a large thunk. She paused, wondering what could have possibly happened before she approached the stairs.

'Tammy?'

There was a pause before Tammy's voice called back, confused, 'Mum?'

'Are you alright?' There was silence, an uneasy silence. Tammy's mother slowly climbed the stairs. She hurried up the last few when her daughter didn't reply. She pushed open Tammy's bedroom door to see her sitting on the floor rubbing her head.

'I tripped,' Tammy complained.

Tammy's mother cast an exasperated look around the untidy bedroom. 'Well, look at the state of your room! I'm not surprised!' she smiled and helped her daughter to her feet. Tammy held her crystal from its cord in her right hand. Tammy positioned herself so her mother's back was to her full length mirror.

Then she threw a look of evil joy at the person on the other side, which was banging and screaming the other side of the reflective glass in a silent plea to let her go.

There we go. Please review!
