I had a dream that I was playing Dark Souls III and found a hidden area that was included in the last DLC. For some reason DASIII has a theme for chuches because I learned that if you go to Church of Yorksha and use an ember by the coffin in the back 10 times while hollowed you hear a maniacal laugh and the floor breaks under you leading you to a new world like what happened in the painting. 

In this world you’re in a long labrynth and can only escape when you reach the top. However the game got more difficult the higher you got. Not did enemies get stronger but you had a higher chance of being invaded despite not having ember. This voice keeps taunting you saying he was punishing you everytime this character finds you. He’s a strong minor type npc that looks like he should be in bloodborne but even if you manage to kill him he just disappears and returns later. Also if you died you’d be teleported to a random part of the labyrinth and bones teleport you back to your last location instead of your last bonfire. The only way to escape without reaching the top is to summon a yellow phantom that has homebound.

It was kind of scary but it was also a really imaginative area and despite me dying basically every time I spawned I never felt frustrated because I knew every death could grant me a luckier outcome and once I got so close to the ending where you had to move a ladder to the opposite side of the tower but a guy up top threw a knife at me killing me. It was really cool.
