Item #: SCP-8187 Object Class: Euclid Special Containment Procedures: SCP-8187 is to be contained in a fully opaque chamber at Site-73, with no reflective surfaces, electronic displays, or recording devices within a 15-meter radius. Access is restricted to Level 3 personnel or higher, and all testing must be conducted using remote analog relay systems. Under no circumstances is SCP-8187’s face to be rendered, described in excessive detail, or shared across digital formats. All images and visual logs must be purged within 18 hours of capture. Personnel assigned to SCP-8187 are required to undergo monthly psychological audits and Class-B amnestic rotation every six weeks. Description: SCP-8187 is a visual-memetic anomaly manifesting as a humanoid figure with heavily distorted facial features. Direct observation, even via image or reflection, causes progressive cognitive and perceptual instability in humans. The entity's appearance is consistent across manifestations: pale, decayed skin, glowing white pupils, facial lacerations resembling surgical sutures, and a lower lip piercing. Note: A recovered visual log (FILE #8187-01) of SCP-8187’s manifestation was previously archived. The image has since been removed following incident 8187-C due to its cognitohazardous effects on staff. (REDACTED per Ethics Committee recommendation – 02/29/██) SCP-8187 affects individuals most severely through eye contact, whether direct or secondhand (e.g. video, drawing, mental visualization). Symptoms occur in three phases: Recognition – Sudden onset of déjà vu, mild anxiety, auditory distortion ("buzzing," "static whispers"). Fixation – Irresistible compulsion to continue viewing the face; self-reported emotions include dread, fascination, or intrusive empathy. Echo – Visual hallucinations of the entity in mirrors, screens, or other faces. Victims describe SCP-8187 “following their eyes” or “waiting in the corners of sight.” After Phase 3 begins, affected subjects report shared hallucinations and refer to the entity as "The Witness." Roughly 30% eventually lose the ability to recognize any face other than SCP-8187’s, including their own. Addendum 8187.2 — Incident Log: During containment transfer on ██/██/20██, a researcher exposed to SCP-8187’s archived image carved a near-perfect replica of the entity’s face into his dormitory wall using a ballpoint pen. Security footage shows the subject speaking to an off-camera figure for approximately 11 minutes despite being alone in the room. Audio log recovered one phrase, whispered repeatedly: "It’s not that it wants to be seen. It’s that it remembers you." Following this, the subject attempted to blind himself using a fragment of the pen. He survived and has been reassigned to long-term psychological containment under Protocol 7-Grey ("Passive Host Reassignment").
