Demencia

Overview
Demencia is a Yume Nikki fangame made by mva-g45. The game gained notoriety for containing hundreds of files from other fangames inside its folders, composing a large part of the game's filesize and the entirety of its ingame soundtrack. Since this issue was made public by players, the creator has since discontinued the game and requested that it is not reupublished.

Despite this, in at least one case the game was suddenly "remade" by other users, updating the game against the wishes of the creator and treating it as if it were an official continuation. These projects were also shut down and removed from play.

Gameplay
You play as a girl named Miko, and enter a dream world through reading books on a pillow.
