I don't think you're paranoid. I too tend to sit in the isles in auditoriums, its easier to get out and for some reason I think the movies just look better from the side. I read somewhere that it has to do with one eye being dominant over the other.

The closest thing to an evacuation I've gone through is when drunk people pull the fire alarm late at night in my college dorm. This normally happens about once a month. It got to the point where the majority of the occupants (my roommate included) would just roll their eyes and try to sleep through the alarm. Kind of scary if you ask me <img src="/images/graemlins/crazy.gif" alt="" />
