For as long as you could remember, your dream didn’t feel like your own. They were off places never seen before, of fire and ash, ice and snow. Every morning you’d wake up and write what you had saw that night.
Some nights were of battles and some of a girl with teal hair. Who was this mysterious girl and why did you dream of her?
This particular night you woke up in excruciating agony. Your right arm felt like it was being torn apart and put back together. That dream was of your right arm being incinerated by a black flame and a dragon killing the person in front of you. 
You were in a cold sweat, clutching your arm like it would fall apart if you let go. Why did you dream these things? What did it mean if it ment anything at all?
You went about your day as usual, going through school and your after school activities. Though it was a far walk, you always seemed pulled to a certain, abandoned park on the east side of the city. You don’t know why but everyday you have to walk by there or you get a sickening feeling in your stomach.
Day by day you go on like this, never knowing what any of it means.
Your parents and friends notice of course. They simply tell you to ignore it or maybe go see a doctor but one friend doesn’t push it away, she listens.
You explain every dream in detail to her and every time she gets a pale face and scared expression but pushes it away.
“I’m sorry, Keiko. You probably think I’m crazy.”
“No, no, not at all. Your dreams are just so interesting, that’s all. Please, keep sharing them with me.”
So you do, every day you tell her something new. One day it’s about a world of monsters, another about getting a third eye put in.
You see anything from a third person perspective, you just see it from the eyes of someone who may or may not be you.
I wake again from that disgusting dream. A dream of human school or other activities.
A dream of people I have never or will never met.
That girl, she looks…familiar some how. A brown hair, brown eye girl…
Could it be…the detectives girl?…
Why would I dream of her? Or wait, maybe a dream of someone who knows that girl?
“Hiei! Come down from the tree, I need to talk to you.”
“What do you want, human girl?”
I drop from the tree. The girls stance was one of fear, maybe a hint of something else.
“My name is Keiko. And I have a question for you. In demon world, is there anything about soulmates?”
“Soulmates? What kind of ridiculous question is that?” The audacity of this girl. “Why would you be asking me? Go ask your…mate or Kurama…or that obnoxious oaf.”
“I can’t because if I’m right then this involves you.”
“Just answer my question Hiei!”
“Tch. Yes there is such a thing. The…soulmates…are connected by dreams of the others life.”
She turns and runs away. I run after her, holding my sword to her throat.
“Explain, girl. Why would this involve me?”
“Ah! Okay, okay. My friend…she’s been dreaming…of the dark tournament…of you.”
“T-the dragon, that you used against Zeru and Bui. She’s dreamt it, felt it even.”
A human girl, dreaming of such a thing.
“And why would I? I have no interest in you humans.”
“Because she might be your soulmate…but also because whatever pain you’ve experienced, she’s experiencing it too.”
“Fine. But only because I don’t want you bothering me anymore.”
