Ranboo's panic room

Ranboo's panic room is a small obsidian room created by Ranboo, hidden underwater past the docks of L'Manberg. It was originally created to be a safe place for Ranboo to go during conflict, but instead became a terrifying place for him where he was forced to confront the voice of Dream.

The room is a 3x3 box made of obsidian, with the only other features being a crying obsidian ceiling, a chest hidden behind one wall (containing 2 pieces of TNT), a jukebox in the floor (now removed), and several signs on the walls. These signs read:
 * "You are fine"
 * "Dont choose a side choose people"
 * "DREAM IS THE REASON"
 * "Techno chose against government"
 * "Everyone should be against dream"
 * "I dont know"

Before L'Manberg's destruction
Ranboo created the panic room on January 4, 2021 while decorating for the Green Festival. He planned to use it as a safe room during the Festival, since he suspected that someone had found out about his betrayals of L'Manberg. After making the room, he remained in it for some time to reflect on his actions and Dream's control of the server, writing signs on the walls as he spoke.

On January 5, the day of the Festival, Ranboo awoke in the panic room before leaving for the event. When he returned later, he heard the Dream voice for the first time. It accused him of blowing up the Community House, then disappeared, causing Ranboo to panic so much that he passed out and entered his enderwalk state.

During the Doomsday War on the next day, Ranboo stashed some of his pets in the panic room to keep them safe. Then, once the conflict had finally died down, he came back to the room and considered the events of the day, briefly contemplating burning his memory book. He was eventually called by Philza and left the room again, not returning for the next few days.

Revisits
Although Ranboo was much further away from the panic room once he moved to the arctic, he continued to visit it for a few weeks.

On January 10, he traveled back there to fetch his pets, but ended up talking to the Dream voice again and passing out. During this visit, he also found a hidden chest behind one of the walls containing 2 TNT that he'd collected during Doomsday.

On January 15, he returned again to confront the Dream voice, but instead ended up discovering that he had been given one of Tommy's discs. This time, he did not pass out, as he left to search for the disc.

On January 18, Ranboo (with Philza's help) was able to retrieve his pets from the panic room with no voice-related issues.

Ranboo returned yet again on January 20 after the Disc Confrontation when he hallucinated the song Mellohi coming from the panic room. The Dream voice did not appear, but Mellohi still would not stop playing. After enough of Ranboo yelling at the voice for an answer, the music finally stopped, and Ranboo opened the panic room's chest to find a newly-created memory book.

On February 1, Ranboo briefly re-entered the room to look for the fourth memory book, but could not find it and quickly left.

Ranboo did not return to the room after February 1, and later died on November 28, 2021. The panic room was briefly mentioned by Boo (Ranboo's ghost counterpart) as he described how pathetic Ranboo had been in life.

Dream voice
The panic room seems to have properties that can affect Ranboo on a deep mental level. The most notable effect is the Dream voice, a part of Ranboo that takes on Dream's voice and can remember everything Ranboo has done in his enderwalk state. This voice has been said to be a manifestation of Ranboo's inner monologue, but other than this, the exact cause of its existence is unknown. The voice has said that it's in Ranboo's mind all the time (since it is him), but can only speak inside the panic room as that is the only place Ranboo "opens his mind" to it.

This voice has appeared multiple times (January 5, January 10, January 15, and January 30) to confront Ranboo and inform him of the things he's done in his enderwalk state, usually in a harsh and accusatory manner. In these confrontations, Ranboo has been reluctant to accept the things the voice says, instead arguing with it and, in most cases, trying to get rid of it altogether.

The voice disappears if Ranboo does not speak to Dream for long periods of time, since Ranboo forgets what Dream sounds like and thus removes the voice's only way of communicating. When this happened after the Disc Confrontation, Ranboo believed he had freed himself from the voice entirely; this was proven false when the voice returned on January 30 in Ranboo's nightmare/hallucination of Pandora's Vault (after Ranboo had visited the prison in his enderwalk state and could therefore remember what Dream sounded like).

The voice stopped appearing once Ranboo was banned from visiting the prison on February 1, 2021, though he remained afraid that it may return if Dream escaped. Dream did escape prison on November 28, 2021; however, because Ranboo was killed that same day and now resides in limbo, it is not known what happened to the Dream voice or if it will ever return.

Other effects
Besides the Dream voice, Ranboo has had other similar hallucinations, such as his nightmare visit to Pandora's Vault on January 30 (though this nightmare was later said by him to be a worsened version of the Dream voice), as well as one instance on January 20 where he heard the song Mellohi coming from the panic room despite him being miles away.

The room also seems to have some connection to Ranboo's memory books. At certain points, Ranboo has found the first page of a memory book overwritten with a message stating the bad things he's done. Ranboo used to be unable to edit these messages in any way, but became able to erase them after he "freed" himself of the Dream voice on January 20 (though the messages still reappeared later). While the exact origin of these messages is unknown, Ranboo has drawn a connection between the panic room and the overwritten pages.

Ranboo has suggested that destroying the panic room would cause something bad to happen, but has not elaborated on this.

Trivia

 * The water outside the panic room serves as white noise to help Ranboo think clearly.
 * Ranboo has confirmed that the creation of the panic room was not planned beforehand; he came up with the idea completely improvised while decorating for the Green Festival.
