Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: SCP-XXXX is contained through elimination of any and all citizens reported to have experienced abnormal behavior and to have tried to discuss nostalgia with their peers. Foundation A.I. constantly monitors social media platforms and internet forums for posts or conversations with key words "nostalgia", "childhood", "the Good Ol' Days", or similar words relating to reminiscent yearning towards one's past and immediately takes them down under the guise of "community guideline violations". Individuals who had their posts taken down will be located and eliminated. Cover stories reporting the eliminated individuals as missing are spread to prevent suspicion. Anyone who witnessed someone experience the different stages of an activated SCP-XXXX and was not activated themselves will be given Class-C amnestics.
Medical professionals are sworn to secrecy upon learning about SCP-XXXX and will be terminated if they refuse to make the oath or if they break their oath, with cover stories typically involving deadly diseases are spread to prevent suspicion. Foundation A.I. is constantly monitoring the internet for any mention of SCP-XXXX by searching for key words like "Brain Seed", "Mind Plant", "Head Flower", or similar words relating to SCP-XXXX.
Discussion of fond memories of one's past are strictly forbidden between Foundation employees. As long as one never engages in conversation surrounding nostalgia, SCP-XXXX will not germinate, even if they converse with one with SCP-XXXX currently active. If an employee attempts to converse about nostalgic experiences immediately disengage and report them to higher clearance personnel.
Description: SCP-XXXX is a small seed that is formed from a mutation of the hippocampus of young children whenever they form a powerful pleasant memory that could be considered nostalgic in their future lives. It is especially present in those born after 1990, as children born after that time form a strong longing towards their childhood. The SCP-XXXX seed is harmless until one starts longing for their childhood once a day for a week straight. Once that threshold is passed SCP-XXXX will germinate and the affected will gain the ability to activate SCP-XXXX's germination within others and begin to try activate it within others, but will also be unaware that they are doing so.
Those with a germinating SCP-XXXX will most often try to activate germination within others through conversation regarding nostalgia, whether it be online, in person or through interacting with or creating social media posts aiming to bring nostalgia upon the viewer, typically referred to as "Nostalgia Baiting". The nostalgia being discussed does not have to relate to oen's personal nostalgia to activate the SCP-XXXX seed. No users interacting with or posting "Nostalgia Bait" nor those recently discussing their nostalgic childhood have reported having any knowledge of SCP-XXXX or its effects. Direct discussion about SCP-XXXX does not result in the germination of the SCP-XXXX seed. As the seed begins to grow further the affected will reminisce on their past more frequently, resulting in the acceleration of the growth of SCP-XXXX.
Taking twenty eight to thirty three days to reach full bloom, SCP-XXXX takes the form of a California Poppy (Eschscholzia californica) and its effects activate to full capacity. The roots of the poppy will fully encase the victims mind and will have started growing around their spine. Victims will begin to crave nothing more than to return to their childhood, convincing them that their current situation, no matter how happy they are, is unsatisfactory. Those hosting SCP-XXXX will begin obsessively participating in activities relating to their childhood, going as far as abandoning their responsibilities. This stage is where most effort is put into spreading germination of SCP-XXXX onto others. After a time frame ranging from 9-16 days after full bloom SCP-XXXX will have completely wrapped around a hosts spine and they will start staying awake through the night to further enjoy their youthful endeavors. This stage of full bloom is reported to be when victims begin putting less effort into trying to begin germination of SCP-XXXX in others in favor of participating in childhood activities. Bearing a fully bloomed SCP-XXXX one month will leave the victims nearly brain dead, the only active part of the brain being the hippocampus. At this stage the host will participate in no other activity other than those they once held dear in their childhood memories, including causing more SCP-XXXX germination, allowing their physical health to completely deteriorate until they eventually begin to decompose. .Bodies have revealed that at this stage of growth neurons have been completely overgrown by roots.
If at any point the affected is unable to partake in childhood activities due to inability to access the proper materials, subjects will pretend they are participating in the endeavor to simulate nostalgia. Amnestics have shown no effects on SCP-XXXX once it has germinated or during any other of stage of growth. If made aware of their current situation, as long as they are not brain dead, victims will non-aggressively panic for approximately five minutes, stop moving completely for approximately thirty seconds, then begin taking part in childhood activities once more, completely forgetting the information they were just given. Experiencing multiple powerful pleasant memories in one past does not result in the formation of multiple SCP-XXXX seeds, it has been reported that only .If the seed is surgically removed before germination, subjects will immediately die and the seed will crumble to dust, this also occurs if the poppy is cut off completely or if the seedling is cut. If petals from the poppy are removed, the subject will not die, rather SCP-XXXX halts growth from the roots and focuses solely on growing the petal back, this process takes about one day. Consistently removing petals from SCP-XXXX has been proven to increase the time it takes for the roots to fully encase a victims body.
Testing Logs:
Test XXXX-01 - 9/23/████
Subject: D6429
Procedure: D6429 was screened to ensure instances of SCP-XXXX seed germination had not occurred, once confirmed, Dr. ███████ will perform open brain surgery on D6429 and remove the SCP-XXXX seed from D6429's brain.
Results: Upon removal of the SCP-XXXX seed, all D6429's vital functions immediately ceased, resulting in the immediate death of D6429.
Analysis: Despite the SCP-XXXX seed showing no evidence of being physically connected to the subjects brain, physical removal will still result in death.
Test XXXX-03 - 10/10/████
Subject: D7483
Procedure: D7483 was confirmed to have a newly germinated SCP-XXXX seed one month before the test. During the time frame between the interaction they were isolated in an empty containment cell and forbidden from any contact with other D-Class or other Foundation Personnel. Open brain surgery will be performed on D7483 by Dr. █████, in which he will cut off the poppy halfway down the stem.
Results: Upon the the poppy being cut off, all D7483's vitals immediately dropped, resulting in the complete shut down of D7483's mind and the death of D7483. The roots encasing D7483's brain immediately shriveled, after further investigation it was reported that the roots showed symptoms of dehydration. The petals of the poppy were also recorded to fall off one minute after the removal of the poppy.
Analysis: Removal of the California Poppy will result in the immediate death of the victim and SCP-XXXX's roots as well as the quick but delayed death of the poppy flower.
Test XXXX-06 - Date
Subject: D3743
Procedure: D3743 was confirmed two have a newly germinated SCP-XXXX seed two months before the procedure. Between the interaction and the operation D3743 was isolated in an empty containment cell, and was forbidden from any contact with other D-Class or Foundation Personnel. After two months, D3743 was terminated. Dr. ██████ will dissect the body to search for traces of the roots of SCP-XXXX.
Results: Upon dissection, Dr. ██████ discovered the roots from SCP-XXXX extendeing and shrinking from the spine into multiple sections of the body. After dissecting the arms, legs, and chest of the body, Dr. ██████ failed to locate the outstretched roots. With disappointing results, Dr. ██████ decides inspect the nervous system of D3743's corpse using a high powered microscope, resulting in the discovery of microscopic roots enveloping D3743's neurons. Interacting with the roots yields no reaction from the body.
Analysis:SCP-XXXX takes control of the body after essentially killing its host's brain by encasing its victim's nervous system in its roots and essentially replaces the brain's function in controlling a host's body.
Interview Logs:
Interviewed: Social Media Influencer (SCP-XXXX-41)
Interviewer: Dr. █████████
Foreword: Interview took place to determine if those affected by an activated SCP-XXXX were aware that their actions could result in the spread of SCP-XXXX
<Begin Log>
Dr. █████████: Are you aware that the image you posted three days ago attempting to trigger nostalgia in others is causing the spread of a lethal phenomenon known as SCP-XXXX?
SCP-XXXX-41: SCP-XXXX? What the hell is an SCP? I'm just trying to gain clout dude.
Dr. █████████: Every single like and comment your post has received has triggered a lethal event in the brains of every person who interacted with your post. Posting that image alone has caused the effects of SCP-XXXX to activate in your own brain.
SCP-XXXX-41: Wait, what? Are you telling me that posting a dumb image for some likes doomed me and my followers to death?
Dr. █████████: That is correct
SCP-XXXX-41 becomes noticeably pale
SCP-XXXX-41: I-I'm gonnna be responsible for the death of over one thousand people? It was just a post! I didn't do anything wrong! They didn't do anything wrong!
Dr. █████████: Please, calm down.
SCP-XXXX-41: Calm down!? I just murdered over a thousand people and essentially commit suicide!
SCP-XXXX-41 runs to the corner of the room and curls up in a fetal position and begins to cry for the next five minutes. SCP-XXXX-41 then swiftly stands up and stiffens. After thirty seconds pass SCP-XXXX-41 begins to seemingly pretend to play dodgeball. Ten minutes pass before SCp-XXXX-41 returns to the interviewing table
Dr. █████████: Are you feeling better now?
SCP-XXXX-41: What? Of course I am, nothing was ever wrong.
Dr. █████████: Do you not remember the fates of you or your followers that you sealed?
SCP-XXXX-41: The only fates I've sealed for my followers is good content my dude.
*Further questioning about SCP-XXXX_41's knowledge surround SCP-XXXX further reveals SCP-XXXX-41's ignorance involving the subject*

Interviewed: Typical Citizen (SCP-XXXX-38)
Interviewer: Dr. █████████
Foreword: Interview took place to further determine if those affected by an activated SCP-XXXX were aware that their actions could result in the spread of SCP-XXXX
<Begin Log>
Dr. █████████: Are you aware that by discussing your childhood nostalgia among your peers, like you did two weeks ago, is causing the spread of a lethal phenomenon known as SCP-XXXX?
SCP-XXXX-38: How could talking about my past cause people to die? I was just talking about how much I miss being a kid, don't you miss being a kid?
Dr. █████████: I will be the one asking questions here, but to answer your first question, to put it short, discussing activates a seed inside your brain that will eventually get you killed, and by conversing about it with others, you are activating that within your peers.
SCP-XXXX-38: Yea sure and paper dragons can come to life and jewelry can make people immortal.
Dr. █████████: How do you know about those SCP's!?
SCP-XXXX-38: What SCP's? What even are SCP's anyways?
Dr. █████████: Never mind that, but your discussions involving reminiscence of your past never have ill-intent behind them?
