The Sunken Place

The sunken place is the name given by Missy Armitage, for the mental prison, she puts her hypnosis clients into. It is used by Order of the Coagula, to trap African Americans in an effort to subdue their minds making them more compliant to The Coagula Method. The surgery used to implant the brain and consciousness of each member of the order into their African American Hosts.

Description
The Sunken Place itself exists within every single mind of each person, that is susceptible to hypnosis. It's appearance varies from person to person, but what they all have in common, is that once placed there, the victim of it is completely cut off from their physical body and are taken to a void where they cannot control said body, nor speak or yell out. In the case of Chris Washington, his sunken place is in deep space with his view of the outside world in the shape of a TV screen like box that is slowly drifting away from him.

Process
Missy begins the process by hypnotizing her victims using a china tea up and a silver spoon as the pendulum. Once the person is in a hypnotic state, they are forced to relive a traumatic experience in their lives. Once there, Missy orders them to sink into the floor, introducing them to The Sunken Place for the first time. Since then, a post hypnotic suggestion has been implanted, which triggers the hypnosis when Missy taps the tea cup 3 times with the spoon. Which sends them back and in the process cause their physical body to collapse. Making them easy to subdue.

Weaknesses
Post-Hypnotic Rest: When the victim is resting for a long time, they eventually escape The Sunken Place, regaining consciousness. Requiring Missy to trigger the suggestion. Chris had unwittingly escaped, by doing so.

Sensory Deprivation: If the victim has their ears plugged, then they cannot hear the sound of the tea cup. Chris used that to escape.

Strong Will: If one's will is strong enough, even post-surgery, the host can briefly take back their body. Which was what Georgina was trying to do.

Camera Flash: The flash from a camera allows the original host personality to take control of their body.
