A discreet object which you find comforting that might help you stay present may be a good idea to have at the conference. Susceptibility to triggers can come from being tired or confused. This is why it is important to try not to be tired or confused in possibly triggering situations. Try to stay awake and alert. Get enough sleep.
Triggers are more than phrases.
They can be pictures, sounds, smells, tastes or tactile or possibly electromagnetic. Any one of these sensations or a combination of them could possibly be used to trigger someone. Triggers can be positive sometimes, like the smell of a favorite food, bringing back a pleasant memory. The added dangers for triggers for ritual abuse survivors are that triggers can be used to open alter states, or very complex programs. These programs could be used to cause a return to the cult or cause someone to hurt themselves or someone else.
