One of the toughest parts of a psychic spy's journey is learning how and when to stop the outside influences from permeating their psyches. It is similar to opening a door in which all manner of thoughts, actions, people and events will pour through. Without knowing when to close the door and how to get rid of all that excess clutter, a psychic can easily get burned out, become less effective or even resort to destructive behavior.
In some instances, psychic spies have turned to drugs or alcohol to mute the voices and turn off the images. There were even officially sanctioned experiments with drugs to determine their effectiveness. The end result, however, is the more drug-free and alcohol-free a psychic spy is, the more efficient and the more reliable they are in their missions.
For this reason, psychic spies undergo extensive testing - not only of their abilities but of their own hold on reality and their own sense of self.
Meditation has been proven extremely effective at keeping the psychics centered and for clearing their minds after a mission.
Some psychics listen to classical music, watch movies or participate in a hobby - from stamp-collecting to sewing, from painting to bird-watching.
In Vicki's Key, Vicki is often very tired after a mission and requires sleep. This works well as long as the psychic "turns off" the psychic activity before sleeping; otherwise, they may continue to dream about the mission, its location and events. This occurs often with Vicki throughout the series, and she's begun to realize that her dreams should be taken as seriously as the mission during wakefulness.
