Class ended. “Hey,” Sara called out to Nerezza in the hallway. “Are you too stupid to remember that I’m supposed to give you a tour?” She asked, even though she had no intentions of doing so. Nerezza’s head snapped up to acknowledge that she had heard, but she said nothing. Sara looked her up and down. A Black tee, black jeans, and black Converses, oddly contrasting with her rosy complexion. “Goth much? God, your clothes are ugly.” Sara threw out, hoping to get a reaction. This was where most geeks said something like, “No, they’re not!” and started crying. Nerezza’s face didn’t change. “What, you’re too dumb to talk?” Sara chided.
“I… prefer silence,” Nerezza said softly. “Now if you would be so kind as to grant me passage.” She said without emotion. Sara realized that she was blocking Nerezza's way.
“Freak.” Sara said, brushing past and shouldering her hard. She glanced back to see Nerezza fingering a necklace that she hadn’t seen before. It must have been under her shirt. Sara squinted at the stone. It was black, so dark that it seemed to absorb the light. Sara shivered and kept walking.
This one was different. Normally, they would cower before me by now, and give up. Realize that I was anomalous. At this time, I am too powerful, less in control. If she does not realize my abnormality soon, a painful end for her will ensue.
Sara was scared. This girl, Nerezza wasn’t normal. She was mysterious, unreadable. She spoke like someone from long ago. However, this only made Sara want to hurt her more. But before she could continue thinking, her vision swam, and she blacked out.
Sara dreamed. She was in a room, pressed against a wall. Hiding. From what? She asked herself. The room was dark. No light penetrated the velvet black, and it seemed alive. The dark was alive. A cold laugh echoed in her ears and something brushed her face. She ran aimlessly, trying to get away. But a part of her knew that no matter how fast she ran, she would never get anywhere.
The dream changed. Sara was in a room lit only by a dusty bulb. The walls were concrete, the floor metal. A small wooden table sat in the middle, with a girl, about Sara’s age, seated at the head. She hummed a soft tune and poured tea into chipped cups for several filthy, decapitated porcelain dolls. The girl looked up, and Sara noticed her white hair and shocking black eyes. The girl smiled. “Oh, good! You’re just in time to join our tea party!” She said, motioning for Sara to sit. She did so timidly. The girl pushed her hair out of her eyes. My hair. Sara thought. Mine? The girl laughed, as if she could hear what Sara was thinking and found it amusing. She fingered the deep black stone on her necklace as she laughed.
“I-I have to go.” Sara whispered, standing up.
“Go ahead. You’ll join me soon enough. And then we’re going to play forever.” The girl replied. Sara tried to run, but there was no door. The shadows reached out and pushed her back, back. The cold laugh returned, mixed with the maniacal chortle of the little girl. Sara screamed, and woke up.
She was back in the hallway, staring at Nerezza’s necklace, as if no time had passed at all. She had a feeling that none had. She stared for a moment.
“Have you not another insult?” Nerezza finally asked, snapping Sara back to reality.
“You… You’re…” She spluttered.
“At last.” Breathed Nerezza, her eyes widening. She walked off, leaving Sara standing in the now empty hallway.

I suggest you add more descriptions and detail; at the moment, it's hard to tell how the dream person and Nerezza are the same.
