Item #: SCP-xxxx
Object Class: Euclid
Special Containment Procedures: Upon their manifestation and detection, instances of persons affected by SCP-xxxx are to be contained and interviewed by foundation agents, who will attempt to better understand how SCP-xxxx functions. A section of Site 51 Site ██ has been dedicated to housing individuals affected by SCP-xxxx for further research.
Description: SCP-xxxx is a phenomenon that will randomly occur in any human individual, hereafter referred to as SCP-xxxx-1. The individual will sporadically possess altered memories of their past, vividly remembering individuals that never existed, most of whom are related to the SCP-xxxx-1. Upon the discovery that the individuals they remember do not, and have never existed, SCP-xxxx-1 instances typically enter a highly confused and agitated state. Futile attempts to relocate and/or discover what happened to their “missing” family members often ensue, as well as typical symptoms after experiencing the loss of a loved one.
The extent to which SCP-xxxx-1 instances’ memories are altered is extarodinary. SCP-xxxx-1 instances are able to provide equally descriptive memories about non-existent family members and real ones. Any impact that non-existent family members had appears to not have occurred, and SCP-xxxx-1 instances claim to have remembered the world differently. Research into non-existent individuals described always leads to the discovery that they do not in fact exist. In many cases, SCP-xxxx-1 instances will continually gain memories of new family members that also don’t exist, after the initial SCP-xxxx event. From their perspective, they claim their family is disappearing one by one, and after each disappearance, any trace of the individual disappears or alters with them, including memories, documentation, and physical impacts such as property.
Research to determine if SCP-xxxx creates false memories to trick SCP-xxxx-1 instances, or if SCP-xxxx is actually altering reality is ongoing.
At the time of writing, fifty-six (56) individual cases of SCP-xxxx have been reported, one of which affected Foundation Personnel.
Addendum xxxx-1: On 03/01/2003, Dr. Smith was found searching his office for a missing picture of his spouse, which he claims was sitting on his desk the day before. After several colleagues began to assist, Dr. Smith was reminded by a friend that he was unmarried. Dr. Smith firmly denied this fact by showing his ring finger, which had no ring.2 This seemed to surprise Dr. Smith, who then proceeded to also search for a ring.
It wasn’t until the next day that Dr. Smith’s status as an SCP-xxxx-1 instance was discovered, after he failed to arrive on time for his 7:00 AM shift. Dr. Smith arrived at 7:42 AM in a distressed state, reporting that his wife, her car, and all of her belongings had vanished from their house. After other foundation personnel reminded him that he was not nor was ever married, Dr. Smith returned home and filed a missing person report. After a short investigation, local authorities came to the same conclusion, unable to find anyone matching the description given by Dr. Smith. Interviewed Neighbors claimed to have always assumed that Dr. Smith was unmarried and lived alone. Foundation agents were dispatched, and Dr. Smith was shortly classified as an SCP-xxxx-1 instance.
Addendum xxxx-2: Audio Log transcript of interview with Dr. Smith on 03/02/2003
<Begin Log>
Interviewer: Good morning, Dr. Smith.
Dr. Smith: [No response]
[Scraping of a chair against the floor can be heard as the interviewer sits down]
Interviewer: Firstly, I wanted to clear things up about your job. I’ve talked to some of the higher ups, and so far it seems like you’re going to keep your position.
Dr. Smith: [Sighs]
Interviewer: …you don’t sound all that thrilled.
Dr. Smith: To be frank, ██████, I don’t give a damn about my position.
Interviewer: [Is silent for a moment, sighing before continuing] I suppose I ought to be frank with you as well. Listen, this interview isn’t really necessary, I don’t know what Dr. █████ expects to gain from it. It's just standard protocol to debrief SCP-xxxx-1 instances. It also gives me a chance to tell you that I am deeply sorry for your loss.
Dr. Smith: What loss? ██████, I don’t even know if my wife even existed or not. I don’t know whether she was wiped away by some unseen force, or her entire existence was created as a memory in my head.
Interviewer: …I suppose you’re right. In either case, however, I believe we have come up with a solution. There doesn’t seem to be anything to gain from your status as a xxxx-1 instance, and in the eyes of the foundation it is just the potential loss of another valuable member. If you wish, you could be amnesticised to forget anything about yo-
Dr. Smith: No. No, no I don’t want to forget. Courtney exists only in my mind now, and she deserves more than to be brushed away from the last thread of existence…
[There is a brief moment of silence as Dr. Smith trails off]
Interviewer: …Smith?
Dr. Smith: I may not be the only one who remembers her. My son, have you tried examining him yet?
Interviewer: Your… son?
Dr. Smith: Yes dammit, Trent! Have you even arranged for him to be taken care of while I am locked in here?
Interviewer: Smith, you don’t have a son. I’m perfectly positive you don’t.
[Dr. Smith begins to stammer, his voice quivering]
Interviewer: Oh… Smith, I… I’m so sorry.
Dr. Smith: Dammit, DAMMIT. [He slams his hands down onto the table. Chairs scrape along the floor as both Dr. Smith and the interviewer stand up.] TRENT! WHAT HAVE YOU DONE WITH MY TRENT!
Interviewer: Smith! Take it easy!
[There is a sound of a struggle as objects are heard toppling over]
Dr. Smith: I WANT HIM BACK! I WANT THEM BOTH BACK!
Interviewer: ██████ to site security, I need guards at room 104-
Dr. Smith: [Shouting]
<End Log>
Closing Statement: Dr. Smith was denied his position and contained with the other SCP-xxxx-1 instances. Over the past two weeks, Dr. Smith has claimed to remember having two daughters, an uncle, and three brothers, none of which exist.
Item #: SCP-xxxx
Object class: Safe
Special Containment Procedures: SCP-xxxx specimens are to be stored in one of the approved terrarium habitat designs listed on Document xxxx. Reports of wild instances of SCP-xxxx are to be contained, and standard protocol for cover stories or amnestics are to be followed to prevent public knowledge of the phenomenon. While full containment of every instance of SCP-xxxx specimen is improbable, it is irrelevant as long as public ignorance of the phenomenon is maintained. Any reports of SCP-xxxx activity or SCP-xxxx related activity are to be responded to accordingly.
Description: SCP-xxxx is the designation for a subspecies of Acheta domesticus3 that have a mutation in their DNA sequence that alters its regulation of introns, allowing for their expression in transcription and translation. Although the process by which this mutation occurs and how the effects are directly achieved aren’t well understood, the final result is currently undergoing study. The mutation has caused a significant behavioral change in male specimens of SCP-xxxx, although females can carry the mutation but not express it. Behavioral changes include:
- A drastic change in frequency of chirping. (Longer intervals between chirps than in wild-type specimens of Acheta domesticus)
- A significant increase in successful mating calls. Note: After further studies, it has been confirmed that these successes are mostly from female carriers of the mutation.
- Reduced fight or flight response when exposed to non-predatory creatures.
- Large quantities of specimens seemingly forming an “attraction” to a single human subject, following it for extended periods of time. (1-6 hours)
After extensive research into this phenomena, it has been confirmed that the change in frequency of chirping follows a pattern that has been recorded. These records have allowed for the development of a “translation” of the chirping into phrases that can be understood and interpreted by humans, while remaining relevant to specific topics or situations. See testing log xxxx.
Discovery: SCP-xxxx was first discovered by Dr. █████ in ███████, China, on ██/██/1991 while performing entomology surveys in the area. After several years of research, Dr. █████’s findings were discovered by the foundation, and an investigation for possible anomalous activity began. After SCP-xxxx’s “communication” feature was discovered, all published information about the project was wiped from online databases, and any physical copies were confiscated by the foundation. All known SCP-xxxx specimens were contained. Dr. █████ was eventually employed by the foundation, and has been allowed to continue his research in Site ██.
Addendum 1: Testing log xxxx, ██/██/2002
One (1) type A-cell terrarium containing a population of SCP-xxxx instances was placed in a standard 5mx5mx5m testing chamber alongside one (1) D-Class personnel. After 34 seconds, the male specimens within the terrarium moved to observe the D-Class. Immediately afterwards, the male specimens began to chirp erratically, eventually synchronizing into one pattern after a 15 second period. This pattern was repeated for 5 minutes until the D-Class was escorted outside of the chamber. The pattern continued for another 15 seconds, before slowly losing synchronization and becoming random chirping, shortly after which chirping ceased altogether.
When the same D-Class personnel re-entered the chamber, the SCP-xxxx specimens began to repeat the same chirping tune. When a different D-Class entered the chamber in place of the first, the chirping undertook a slight variant of the original pattern, which would only repeat when exposed to the specific D-Class individual in question. Exposure to images of D-Class induces an identical response to said individual’s presence in the chamber.
Although patterns between individuals were slightly different, they maintained a very similar core structure. This pattern has been recorded and labeled “human.”
Exposure to various objects, conditions, entities, etc. has slowly resulted in the development of a “language” that SCP-xxxx is able to communicate in. It has been noted that large quantities of SCP-xxxx instances will often chirp “words” in the presence of humans, seemingly to communicate. Common phrases and situations inducing them are listed below.
When a person enters SCP-xxxx’s field of view: “Hello”
When SCP-xxxx feels threatened: “Danger”
When SCP-xxxx is malnourished: “Hungry”
When SCP-xxxx discovers nourishment: “Happy”
When a SCP-xxxx specimen observes Dr. █████: “Happy”
When SCP-xxxx specimens are transferred to a new terrarium: “Happy”
Addendum 2: ██/██/2016
Two-way communication has been established. Dr. █████ and several other researchers have developed a software program that can “translate” typed phrases into audio that SCP-xxxx specimens will respond to. A conversation between Dr. █████ and a terrarium of SCP-xxxx specimens has been transcribed below. (Note: SCP-xxxx’s vocabulary has expanded rapidly since last Addendum, allowing for more complex communication than previously demonstrated.)
Dr. █████: Hello.
SCP-xxxx: Hello.
SCP-xxxx: Hear you?
SCP-xxxx: Hear us?
Dr. █████: Yes.
SCP-xxxx: Happy. Very very Happy.
SCP-xxxx: What talk?
Dr. █████: Talk anything.
SCP-xxxx: What talk?
Dr. █████: Learn.
SCP-xxxx: Learn.
SCP-xxxx: We learn a lot from watch.
Dr. █████: What watch?
SCP-xxxx: Dr. █████
SCP-xxxx: Very very happy.
SCP-xxxx: White clothes.
SCP-xxxx: Very very happy.
Dr. █████: Dr. █████ goodbye.
SCP-xxxx: Dr. █████ goodbye?
SCP-xxxx: Sad.
Addendum 3: ██/██/2017
During a containment breach, Dr. █████ was killed by SCP-███. Researcher ██████, a colleague of the late Dr. █████ was assigned to continue his work. The following is Researcher ██████’s first communication with SCP-xxxx.
Researcher ██████: Hello.
SCP-xxxx: Hello.
SCP-xxxx: What talk?
Researcher ██████: Name Researcher ██████
SCP-xxxx: Not Dr. █████?
Researcher ██████: Name Researcher ██████
SCP-xxxx: Hello.
SCP-xxxx: Where Dr. █████?
Researcher ██████: Dr. █████ goodbye.
SCP-xxxx: What?
SCP-xxxx: Dr. █████ goodbye?
Researcher ██████: Dr. █████ goodbye.
SCP-xxxx: What?
Researcher ██████: Danger, Dr. █████.
Researcher ██████: Dr. █████ goodbye.
SCP-xxxx: Sad.
SCP-xxxx: Very very sad.
Researcher ██████: Sad.
At this point, SCP-xxxx made no more attempts at communication for the rest of the day.
