Object Class: Safe
Special Containment Procedures: SCP-4370 is to be kept on a three (3) by three (3) by two (2) meter room, SCP-4370 must rest on a ninety (90) cm wide and one hundred-seventy (170) cm long bed, a standard containtment door is to be used to enter SCP-4370's containtment cell, only level 2 cleareance personnel have access to it's containtment cell and testing must be conducted with the presence of at least one (1) armed guard on it's door to ensure the subjects don't try to escape the containment during testing.
Description: SCP-4370 is a squared blue pillow, measuring forty (40) cm long and wide, this pillow has a noticeable lack of stuffing, and the pillow itself seems to be heavily worn, the material that forms it's unknown, it heavily resembles cotton, however some of it's caracteristics indicate it's another material not yet discovered.
SCP-4370 is capable to keep a constant temperature of 17 ºC, exposure to colder or warmer temperatures and/or objects doesn't seem to change it's temperature at all, and test subjects expose desires of sleeping with it again, despite reporting discomfort about doing so.
Tests are to be always conducted with two (2) test subjects, one must sleep using SCP-4370, while the other sleeps without it, when this happens subjects will fall asleep for an indefinite amount of time, normally ranging between ██ and ██ hours, when the subjects wake up, they become instances of SCP-4370, accordingly named SCP-4370-1 and SCP-4370-2.
When the instances wake up, SCP-4370-1 will become really possesive of SCP-4370, and besides displaying an infantile behaviour, nothing else differs from their normal personality, however, SCP-4370-2 will elaborate convoluted plans to steal SCP-4370 from SCP-4370-1, it's personality is completely overwritten and no traces are left from it's old personalty, when SCP-4370-2 manages to steal SCP-4370 from SCP-4370-1, SCP-4370-1 will become highly aggresive, usually resorting to biting, slapping, and scratching SCP-4370-2, however, if it doesn't comply to give SCP-4370 back, SCP-4370-1 will result in using more aggresive techniques such as strangling, punching, eye-gauging and asphyxiating SCP-4370-2 until it dies, or it complies to give SCP-4370 back, if SCP-4370-2 complies, things will go on as usual, however, if one of the instances die, the anomalous effect of SCP-4370 ends, usually the other instance faints as the effect ends.
SCP-4370 was discovered in ████████, ██████████, Spain, the 26/07/20██, discovered by Agent ████████ as SCP-4370's effects ended up in a death of a ██ year old boy by the hands of his best friend █████, a ██ year old girl, Class-B amnestics were administered to everyone involved and the boy's family was told that the boy died in a traffic accident.
