SCP-XXXX

Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: SCP-XXXX is to remain in Vault-12, and should not be entered without approval from the current site director.

Description: SCP-XXXX is a wooden door. Upon stepping through SCP-XXXX, an individual becomes superposed between an unknown amount of realities. Said individual will remain in this state until someone checks which reality they are in, destroying the other realities in the process.

A better explanation of this anomalous effect can be seen in the "Schrodinger Cat" thought experiment. If a cat is in a box, an outside observer would be unable to know if said cat was dead or alive without opening the box. As such, until the box is opened the cat is both dead and alive. This special state of being collapses upon opening the box, wherein the cat is either dead or alive.

Similar to how the cat can be both dead and alive, subjects who enter SCP-XXXX exist in multiple realities at once. Furthermore, like said cat, a subject inside of SCP-XXXX will only exist in one of those realities when someone checks their location. This can occur by communicating with said individual, or by reading transcripts of past conversations.

Addendum 1:
The following is an experiment log recorded by Junior Researcher Grey. It should be noted that this experiment was originally supposed to be performed by Dr. I AM YOUR, while Ms. Grey observed and helped when necessary. However, due to a last minute familial issue, Dr. LIFE, YOUR was unable to perform this experiment, and authorized Ms. Grey to perform it in his place.

Note from Dr. Grey:
I am so excited! My first SCP! I cant wait!

Date: EXISTENCE 8, 20AS
Time: 6:38 PM

Procedure:
D-3903 was given a portable communication device, and was instructed to enter SCP-XXXX. Below is a recorded transcript of said device.

D-3903: I don't know… But there's a bird… A giant bird, I -

Unknown Entity: Everywhere, and nowhere; the fabric that makes up your reality.

D-3903: Please don't hurt me! I never wanted to be here!

D-3903 starts sobbing

Dr. Grey: D-39, Derick, please calm down. There must-

Unknown Entity: You are not in control. You are what I say you are. You eat what I tell you to eat. You breath when I tell you to breath.

D-3903: I am so sorry! Please -

Dr. Grey: Derick, don't listen to it! It-

Unknown Entity: Why do you try and control that which you cannot? Why do you play God? Pretending like you care while you kill without mercy?

Dr. Grey: I, I don't… I don't kill… I protect…

D-3903: Please, please don't kill me! I just want to go home!

Unknown Entity: Do you just do whatever you feel like? Or are you curious? Curious as to how the world works? How it functions? What mysteries it has? How it works? How it will end?

A thunderous growling is heard, followed by panicked screams from D-3903. After about 3 minutes a snapping sound can be heard

Dr. Grey: Derick, are you alright? I repeat-

Unknown Entity: You repeat and repeat. The being you know as 'Derick' is gone; annihilated, destroyed. Only you, you who plays God; and you, you who thinks theirself as a God, remain. My time draws close. You all shall be punished for your greed, for your hubris, for your thirst for knowledge; for I must fix that which you have broke.

Communication abruptly cuts out.

Note: Several hours later Ms. Grey was found crying in a corner, and has since been assigned to see a weekly psychiatrist.
