In any situation that the GM feels is stressful, he will roll 3d. On a 6 or less, you have a flashback. The GM will roll whenever you miss a Fright Check or make the roll exactly, and whenever you fail a self-control roll for another stress-related disadvantage.
Make a self-control roll whenever anyone lingers nearby, watches over your shoulder, etc. If you fail, you lash out at that person just as if you had Bad Temper.
During the full moon, you are extremely emotional and volatile, while on nights of the new moon you are very passive (you temporarily suffer from the Laziness disadvantage, B142). While the moon is waxing, you are focused and pleasant; while it is waning, you are apathetic and a little touchy.
