Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept folded within a secure locker in Site-37. The object must only be erected for testing purposes, with experiments being limited to level 3 and above research personnel and Outpost-37/XXXX.
Description: SCP-XXXX designates a dark-blue tent made from polyester 200 cm in height and 80 cm in width. Four steel bolts were found at its place of discovery that held the object in place and are connected to the four tent poles. Except for the black bottom, the inner tent is also dark-blue.
The anomalous effect of SCP-XXXX occurs whenever a human subject falls asleep within it at a distance of 20 km from the next living human at night, followed by the same individual waking up around an hour later. From this point onward until sunrise, the subject will experience vivid hallucinations while the material within the tent changes repeatedly, while every sound produced within becomes inaudible on the outside. Subjects who entered this stage reported a sleep paralysis merely excluding the eyes, which also causes them to stay awake throughout the entire experience. Exposure to SCP-XXXX leads to several mental problems, including depression, anxiety and post-traumatic stress disorder.
Discovery: SCP-XXXX was discovered by field agents within the Rocky Mountains following the suicide of Agent Jackson during his holiday trip. Initially, the local hunter Tom ███████ recovered the incident site and subsequently alarmed the nearest police department, which attracted the attention of the Foundation. The anomalous properties of the object were revealed by Agent Jackson's notes he wrote down the morning after in an attempt to process the experience. All civilians involved were amnestitized and SCP-XXXX secured.
Addendum-01/Notes by Agent Jackson
Foreword: These are the writings created by Agent Jackson in the aftermath of SCP-XXXX's effects.
I don't know where to start. The Foundation always expects of its agents to cope with everything, every monster and nightmare. But whatever I've seen last night was anything but.
I put out the campfire at around 10 o'clock and went bed. Should have been quite a resting experience considering the hike was pretty draining. Around an hour after falling asleep, I awoke. Unable to move, my eyes rapidly scanned the tent for any indications that could explain my state, but none ever came. A wolf howled in the distance. Then silence.
A woman screams from somewhere, but it sounded like she flew right over me. Next those hands — those fucked up black hands emerged on the tent and stroked in an almost lovely manner, as the tent suddenly fell down. Or it didn't? I don't know. Silence once more, only broken by sudden screams.
A car pulled by and people stepped out who were apparently looking for a murderer. Then I saw that the zipper had vanished. I tried to scream, make them notice me, but they just walked by my tent as if I wasn't there. Then a swarm of insects attacked them, with one of the men falling onto my tent. A dark silhouette quickly torn apart by whatever those insects were laid over me until the tent ripped open and I saw his face. It was my wife! The only one still showing me love in my life, now perforated and dead. I pressed my eyes shut and could only open them after the sounds stopped, which revealed the sunlight. I don't where they took her.
No help will come. There's no signal out here and civilization too far away to not make me go to sleep again. I can't do this again.
