Special Containment Procedures: SCP-[...] is to be contained within a standard anomalous object locker at Site ██. The locker is to be secured with a combination lock, with the combination changed on a weekly basis. Access to SCP-[...] requires Level 2 clearance and must be approved by two senior researchers. All personnel handling SCP-[...] must wear protective eyewear with embedded amnestic-releasing lenses to prevent accidental exposure to cognitohazards.

In the event of exposure to SCP-[...]'s cognitohazards, affected individuals should follow the emergency procedures outlined on the journal's cover (see Addendum A). Any personnel experiencing severe symptoms or showing signs of prolonged exposure are to be immediately quarantined and provided with specialized treatment.

Due to the nature of SCP-[...], all research and testing must be conducted remotely, with researchers observing the journal through a closed-circuit video feed. No direct contact with SCP-[...] is permitted without prior approval from the Ethics Committee.

SCP-[...] is a hardcover journal, approximately 200 pages in length, with the words "Cognitohazardous Journal" emblazoned on its cover. The journal contains handwritten entries detailing the daily life of an unidentified individual, aged between 16 and 23 years old, who is seemingly aware of and sensitive to various cognitohazards. The journal itself is not anomalous, but the entries within are filled with potent cognitohazards, making it a significant containment risk.

The cognitohazards within SCP-[...]'s entries manifest in various forms, including but not limited to:

• Auditory Hazards: References to specific sounds or musical tones that, when imagined, can induce severe headaches and disorientation.
• Visual Hazards: Descriptions of intricate patterns, symbols, and geometric shapes that cause discomfort, nausea, and, in some cases, temporary blindness.
• Conceptual Hazards: Discussions of abstract concepts or ideas that, upon comprehension, can lead to cognitive dissonance, confusion, and, in extreme cases, psychosis.
• Literary Hazards: Excerpts from fictional works or poetry that contain hidden messages or codes, causing readers to experience paranoia and delusions.

The subject's self-description within the journal also contains cognitohazards, making it impossible to accurately describe their physical appearance or personal history without risking exposure. All attempts to trace the subject or identify their current whereabouts have been unsuccessful.

SCP-[...] was recovered from a public library in ███████, ██, after several patrons reported experiencing severe headaches and disorientation while reading a particular journal. Foundation agents were dispatched to retrieve the journal, and subsequent testing confirmed its anomalous properties.

The following is a transcription of the warning message found on the cover of SCP-[...]:

Journal Entry: [REDACTED], 20██

Another day, another battle against the unseen forces that lurk in the shadows of my mind. I awoke to the familiar [COGNITOHAZARD REMOVED], a relentless melody that haunts my dreams and lingers long after I've silenced my alarm. As I stumbled out of bed, I felt the weight of the world pressing down on my shoulders, a sensation I've learned to associate with the presence of [COGNITOHAZARD REMOVED].

In my morning routine, I encountered the usual suspects: the [COGNITOHAZARD REMOVED] in the mirror, the [COGNITOHAZARD REMOVED] on the breakfast table, each one a potential trigger for my fragile psyche. I've developed strategies to navigate these hazards, but the constant vigilance is exhausting.

At school, I found myself in a [COGNITOHAZARD REMOVED] class, where the very concept of [REDACTED] seemed to twist and contort before my eyes. I could feel my sanity slipping as I struggled to make sense of the [COGNITOHAZARD REMOVED] equations on the board. Thankfully, my training kicked in, and I managed to avert my gaze before the full force of the hazard took hold.

During lunch, I sought refuge in the company of my friends, but even their presence couldn't shield me from the [COGNITOHAZARD REMOVED] that seemed to infest every corner of the cafeteria. I could sense the malevolent intent behind those [REDACTED], as if they were designed to [DATA EXPUNGED].

As the day wore on, I felt my mental defenses weakening. The [COGNITOHAZARD REMOVED] in the hallway seemed to whisper secrets that threatened to unravel my sanity. I hurried to my next class, desperate for a reprieve.

But the respite was short-lived. In [REDACTED] class, we delved into the works of [COGNITOHAZARD REMOVED], a literary genius whose words seemed to dance on the page, revealing hidden truths that no one should ever know. I felt my mind bending, straining to contain the flood of [REDACTED] that threatened to spill forth.

Journal Entry: [REDACTED], 20██

Who am I? I peer into the mirror, searching for a glimpse of my true self, but what I see is a [COGNITOHAZARD REMOVED]. My reflection seems to shift and distort, as if my very identity is a puzzle, forever changing and elusive.

I am a [COGNITOHAZARD REMOVED]. My age, a mere number, fluctuates between 16 and 23, a constant reminder of the uncertainty that defines me. I am neither here nor there.

My hair, a [COGNITOHAZARD REMOVED], defies description. It dances in the wind forming patterns that destroy my sanity. My eyes, windows to a tormented soul, reflect the anomalies that I witness daily.

My body, a vessel for the anomalous, is a canvas of [COGNITOHAZARD REMOVED]. Tattoos of [REDACTED] cover my skin, each one a reminder of the hazards I've endured. These marks are not mere decorations; they are a language that only the cognitohazards understand.

I am a wanderer, a [COGNITOHAZARD REMOVED], seeking refuge from the storm of anomalies that pursue me. I've learned to navigate the treacherous paths that others dare not tread. My mind has become my greatest weapon and my heaviest burden.

In this journal, I attempt to relate my experiences, to give form to the formless horrors that haunt me. But even these words, carefully chosen, cannot fully convey the [REDACTED] that is my existence. I am a paradox, a [COGNITOHAZARD REMOVED], forever bound to the pages of this journal, yet always just out of reach.
