Interesting. I would have come to the oppisite conclusion, namely that lsd would increase the response to fearful stimuli. It makes sense. My friends who have had bad trips weren't triggered by fearful, external stimuli. They were caused mostly by repressed emotions or thoughts that lsd or mushrooms brought to the fore. From my experience and observations, bad trips can be powerful experiences that have a positive effect, forcing you to face that which you have hidden away. Of course, it can be damaging as well.
