Death 13 but an SCP. Baby that when it sleeps at the same time as people nearby gives them death inducing nightmares. Kind researcher is eventually taken off caretaker duty due to 'emotional attachment'. Cold caretaker has nightmares. Eventually succumbs to the effect despite not sleeping near baby. Baby dealt with remotely. Staff has wide spread nightmares. D-class caretaker fails to relieve nightmares. Kind researcher reinstated as caretaker to prevent mass causalities. Effect relieved and researcher perma-caretaker with no problems.

A story "The Empty Town" (or some ominous horror title like that) that when you read it without anyone else in the room causes everyone else to disappear/the reader to be transported to alternate dimension with no people. Supposed to mirror feeling of reading scp articles late at night.

Melting Man
Humanoid entity composed water doesn't know who they are, constantly questioning what they want and how they get it (begging, intimidation) as clues on who they are. Wants to take other people's identity from them.
Discovery: Terrified woman talks about discovering a monster on her
SCProcedures: As of incident XXXX-1 the cell is to be waterproof and airlocked. SCP-XXXX-1 and XXXX-2 (Melting man and previous-melting-man researcher) are contained in seperate cells here
Incident xXXX-1: Melting man escapes, steals researcher's identity.
Ammendum: ex-melting-man researcher points out that if they are an anomoly despite all evidence (DNA tests, biological scans, psych evaluations, ect ect ect) then the woman from discovery report could be it, anybody in the entire town could be anomolous, its hypocritical to keep them locked up

Well that goes down infinitely. Don't actually need to breathe or eat or age in the water (only the breathing is logged in the article)
Discovered when a villager fell into the well and was under the water for over 10min before they were recovered but was still alive despite the fact they took big mouthfuls of water. Foundation intervenes after rumors spread
Exploration log: Agent goes down the well with air tank and is reeled back up after they freak out, claiming something grabbed their leg.
CONSIDER: Of note is that only 150m of cable was dispensed but 450m of cabling came back. Do I really need the well getting exponentially deeper on the return trip? Is that relevant to the story? Can I just describe how damn deep it is by the agent being like "is this how deep a well normally is?"
Consider: "Subsequent explorations of SCP-XXXX have descended to X metres but have not encountered any unusual phenomena besides the depth of the well."

Dude who has an innocent/victim presence. The horror is that he's super evil, just an abuser. Discovery logs are where its at, starting with the fact that a researcher was missing from work and when the foundation took her in for investigation she was found to be under the effect of a cognitohazard. Turns out the cognitohazard is her husband. Would making her the lead researcher be a thing? Maybe SCProcedures state that she is to believe she is the head researcher, but actually is merely being used to study the scp under watch? And attempting to stage a containment breach (which she does not have the authority she believes she has to pull off) will have her removed permanently from the position, or administered amnesics. Maybe do something about how the foundation and the scp are both excreting THEIR reality over her to control her.
At the end there's an ammendum stating she has escaped from the facility and must be recovered. Then another saying that she has been seen with a group of interest and is considered secured by that goi/unrecoverable.

A phenomenon where subjects (probably spread around the D-Class) can feel when they are being watched, which the foundation is initially either worried about the phenomena or ignoring that its them inducing the paranoia. Gradually, subjects can detect finer details about the people watching them. Perhaps it starts off with the foundation realising the subjects can get information about researchers/security watching them, but later also implied that Something Else is watching the subjects (and thus the foundation), which makes it a double info breach.
Phenomena needs some sort of cause for the foundation to contain it.
