.Flow

Much like Yume Nikki, little is known about the main protagonist, a girl named Sabitsuki, about whom very little is known. Similar to Madotsuki, the protagonist of Yume Nikki, Sabitsuki lives in an apartment with a bed, a single game console, a television, and most importantly, a personal computer which she uses to enter a state known as "flow." While in flow, Sabitsuki (and the player) enter an surreal immersive reality linked to her psyche which she can explore in order to find 25 "effects." Exactly who Sabitsuki is, what she has gone through, and even what kind of world she lives in is entirely up to the player to interpret based on what they see and experience while in flow.
