Laconic Description: SCP-5131 type of sleep paralysis affecting Foundation personnel wherein they will experience a sleep paralysis hallucination of D-13131, a mysterious D-class personnel. Prior knowledge of the existence of SCP-5131 is believed to increase the chances of experiencing it, but personnel usually don't experience SCP-5131 more than once.
During the hallucination sufferers will feel pain correlating to any situations in which under their supervision D-Class personnel were killed. For example, a researcher studying SCP-106 will feel the pain of his femur being broken in a similar manner to how a D-Class in the femur-breaker would feel it. O5-5 reports feeling the collective agony of all D-Class ever killed because of the Foundation.
