Oversomnia

Overview
Oversomnia is an English Yume Nikki fangame created by Wambysock. It was made for Dream Diary Jam 2 in RPG Maker 2003.

Gameplay
Oversomnia is a traditional fangame. You play as a boy named Irving, and your goal is to explore his dreams while collecting effects. You enter the dream world by sleeping in bed and save by using either the closet or the phone in the room. The latter allows you also to view stats (how many times you slept, the number of effects got and the number of events you have triggered) and change the menu theme.

Unlike many fangames, there is a NPC (seated behind a booth next to the Nexus doors) who will provide Irving with hints and temporary item abilities for a fee.

Its has a Bestiary too, where you can learn a little bit more about the NPCs

Plot
There is currently very little plot. According to the creator, Irving is part of a "dream club" whose three members gather or otherwise use other means to share the dreams they have. Therefore, unlike many protagonists Irving is willing and able to leave his room as he pleases.
