Per 
Special Containment Procedures: SCP-XXXX effected personnel are to be temporarily removed for memetic screening. They are to be returned to work after confirming that no unusual mental effects are present.
Description: SCP-XXXX is an anomalous phenomenon in which several Foundation personnel employed at Site-113 experience memories of an individual referred to as Junior Researcher Manuel Mather. There are currently no records of any individual matching Mather's description ever having worked at the Foundation, and no evidence of their existence other than memories is present. Effected personnel universally describe Mathers as a short, middle-aged woman with black hair and blue eyes.
Research into this phenomenon is ongoing and currently headed by Senior Researcher Jason Krans. More information will be added to this file as it is discovered.
