A videogame created by Kikiyama where you play as a girl named Madotsuki. You explore her dream world and collect various effects to help you. This game has been described by many as genuinely disturbing due to the nature of the dreams, but has a large group of fans.
I played Yume Nikki last night and it scared the pants off me.

A very melancholy, and surreal game about a social introverted girl who won't go outside(probably due to some sort of personality disorder) and has disturbing/psychedelic dreams. Draws heavy inspiration from games such as Earthbound and LSD dream emulator.

The developer Kikiyama created the game back in 2004-2007 and has not been heard of for years since (fans theorize he/she is dead and this game was their last cry for help).
Timmy: OMG undertale is amazing!1!1!1!1!

Philip: Oh, that reminds me of a game called Yume Nikki.

Timmy: Yume Nikki? That sounds like a rip off of Undertale!

Philip: No.

A chaotic and fun discord server with lots of delusional shenanigans. Contrary to unpopular opinion its admin is not a e-girl nor an e-kitten, however one of the admins will occasionally dabble in such activities
"Hey did you hear about the admin in the Yume-quarium server that turned to e-girling?"
