A girl realizes that strange things are happening in her life.
At first images of unknown people appeared in her mind then she started imagining pictures of random things too.
Like the number on the page of a book, or a bunny shaped lamp. She comes to understand that exactly at 9:06 in the morning she would see in real life the thing that appeared in her mind the previous day.
As a manga artist she also figured out something was wrong with the characters she created. Whenever she finished drawing something she would come across a comic with an identical character.
When she couldn't stand not understanding what was happening to her she decided to find answers with her psychologist friend, noting down anything that happened to her.
