Triggers can be anything. From someones smell, to a movie, to a certain color. Sometimes you recognize them right away, other times you may just react & not realize what's going on. (See "Grooming") I don't believe you should share these with anyone, especially not the specifics as to why, unless you absolutely trust that person. Even then you might not want to. Without counseling, proper, specific help, you might not know what they are right away. Or you know how you react to something & try to avoid it without knowing why.
