Once there was a little girl who had no friends and was very lonely.  She decided to make an imaginary friend but he was different, he was a black ghost human named Dark.  As the girl grew older she forgot all about Dark and made real friends which made Dark want revenge.  Every night, one by one of her friends in her nightmares will be the one who will get injured badly in real life by Dark.  She decided to make a potion and got all the ingredients except one, a feather.  She threw the potion at Dark and it worked, all of her friends were ok and Dark disappeared.  Since she forgot that one ingredient she still has nightmares about Dark.  When she sleeps every night, a black ghost stands in her room and it still follows her…
