Dream Walker

Dream walkers are rare in today's world, they've gone from being known, to merely a myth. Anyone from the royal bloodline usually had the power back in the days when King and Queens, Pharaoh's and Emperors existed, but now it seems that the gift has gone extinct, and with little knowledge on the power itself anyone who does have it never tells anyone. Dream Walkers weren't born with their powers, they would inherit their powers on their 18th birthday. Everyone in the world on their 18th birthday awoke with a tattoo on their wrist that only they could see, the words were the first ones their soul mate would say to them, and once they were said by their soul mates, everyone could see the words, knowing that that person had been claimed.
Katt Evans just graduated High School, and for her entire life she has been the outcast. She never knew why but people seemed to be allergic to her, metaphorically. She'd been lucky enough to find one best friend, but s/he died months ago in a tragic accident. Katt always loved dreaming, if she wasn't consumed in her music or art she would often doze off, or day dream. On her 18th birthday she awakes with the words "You're different..." written in dark ink on her wrist. Everyone had one, some were visible to others, some weren't yet. That night after she's fallen asleep and is happily tucked away in her dream, she comes across a sign in her dream that reads... "WARNING: You're entering someone else's dream."
