The Controlled Cognitive Reformatting Multi-Sensory Environment, or CCRME, is a soundproofed room with adjoining office located in the basement of Marshall Redgrave’s home at the Mission. It is not easy to find, concealed, as it is, down an out-of-the-way set of stairs and behind an unmarked door. Three walls of the room are covered with color TV sets; the fourth contains the entry door and a blackened one-way mirror that faces into the office. In the center of the room is a chair resembling something out of a dentist’s office, with stirrups at the feet and restraints on the arm and headrests. Above the chair dangle a terrifying array of light fixtures, speakers, audio headsets, electrodes, and other devices. An IV drip stands menacingly in one corner.

The CCRME is Marshall’s brainchild, who designed the chamber with assistance from others at Project SANDMAN. On a rudimentary level, it can operate as an interrogation space for especially difficult subjects — but that is not its intended purpose. As designed, the CCRME functions as a sort of early ‘70s version of a SANDMAN “brain hacking” center, a place where Marshall can experiment with deconstructing and reconstructing a subject's identity, erase and implant memories, alter goals or insert specific objectives, and ameliorate or create harmful psychological tendencies.
