SCP-5001 “Mandela Effect”
Object Class: Euclid
Special Containment Procedures: Internet chatter is to be constantly monitored by MTF Kappa-10 “Skynet” for any mentions of SCP-5001. If groups or individuals are seen discussing, investigating, or otherwise trying to understand SCP-5001, they are to be immediately taken into custody, interrogated, and, depending upon the severity of their contributions to understanding SCP-5001, administered Class A amnestics and have false memories implanted, or terminated.
Description: SCP-5001 is a series of CK-Mandela-class break in reality events. These events have occurred at multiple points throughout history. Most notably and most recently, the event beginning at █:00 AM EST on 9/██/200█, and lasting for a period of ██ hours. This event is believed to have resulted in the deaths of at least █████ individuals across ██ different timelines.
The events themselves are not fully understood at the present moment. All that is know is that, every time an SCP-5001 event occurs, time breaks into several different possible timelines, the least on record being 2, and the most being ████. After the SCP-5001 event initially occurs, it continues until all possible timelines have converged at another single point. Resulting in individuals believing that the events which occurred during their timeline are the truth.
Discovery: SCP-5001 nitially brought to the Authority’s attention when it was discovered by John ██████ on 12/15/200█. While browsing the popular forum site ████, he posted a thread titled “Does anyone remember 9/██/200█? Because I feel like I missed something.” 12 hours after his initial post, he was taken into Foundation custody and then interviewed about his recollection of the events of 9/██/200█.
Addendum 5001-01: Interview with John ██████.
Foreword: The following is an interview conducted between Lead Researcher Dr. Cornelius Dayne and John ██████ shortly after his delivery to Site-020.
<Begin Log>
Dr. Dayne: This is an interview between Dr. Cornelius Dayne, and John ██████. Mr. ██████, do you understand why we brought you here?
Mr. ██████ shifts around in his chair uncomfortably.
John ██████: Is this because I ran that red light last week? I was late for work and I need this job man.
Dr. Dayne: No Mr. ██████. This is about your questioning the events of 9/██/200█. Do you have any recollection of that day at all?
Mr. ██████ looks visibly relieved and adjusts himself.
John ██████: Oh, that’s what this is about? Um okay. I posted it because I felt like something was off, like the whole day didn’t happen you know?
Dr. Dayne: I understand. You feel like the whole day just didn’t happen, like you missed it?
John ██████: Exactly like that doc.
Dr. Dayne: Have you considered the possibility that you blacked out, or possibly just slept through the day?
Mr. ██████ begins to become visibly distraught.
John ██████: I used to black out when I would drink, forget what happened the day before and all. But I gave up drinking years ago doc. I’m sure I wasn’t drunk, you gotta believe me.
Dr. Dayne: I believe you sir, I just wanna see if we can understand what happened, that’s all.
Mr. ██████ becomes distraught and refuses to answer anymore questions over the next 2 hours.
