Yume Nikki

Yume Nikki is a free psychological adventure game created by Japanese developer Kikiyama in 2005. Through the course of Yume Nikki, the player will assume the role of Madotsuki, a severe shut-in who spends her time sleeping, staring at the test pattern on her TV, or playing the same depressingly monotonous game over and over. The player will not be able to have Madotsuki leave her self-imposed prison, shaking her head in disapproval at every attempt to make her go outside.The only way of escaping this is to dream via sleeping in your bed. While sleeping you can freely explore 12 differnt levels all with there own themes but all some how giving off a lonely and creepy atmosphere.
Their is no clear story to the game but it is all up the player and how they interrupt what goes on in the game.
