24-Hour Amnesia - A Collaboration Story

[KHRxHOTD]

In the "Scary Noises" map,

Spoiler below!

I found the key, and I unlocked the room again with the spair key that I've found in the cellar, but then, when I get in the room, the door locks herself and then I hear a monster grawl, but the door doesn't break. The grunt keeps hitting the door, but it refuses do break, and I don't know what to do, because I thought that maybe I have to die to finish the map, but I don't know... Can someone help me? I have no clue...

There should be a book on the table. Just throw it in the fire.
