Nightmare programs trigger anxiety and panic attacks within the victim by stimulating the neural circuitry representing the amygdala and hippocampus. The target ego must make a WIL x 2 Test. If they succeed, they are shaken but otherwise unaffected, suffering a -10 modifier to all actions until the end of the next Action Turn. If they fail, they suffers 1d10 / 2 stress damage and are overcome with panic. This causes them either to blindly flee, have a nervous breakdown, or cower in frozen shock (gamemaster's discretion). This panic episode lasts for 1 Action Turn per 10 points of MoF.
