I was maybe 4 or 5 when I saw Jaws. It gave me one nightmare. I got over it. I've lived here in Florida almost my entire life. Never been worried about going into the water here in the Gulf. I know sharks are out there. I've seen 'em. Still, I'd be on the board with the feet dangling in the water, goofing off while waiting for the next wave. Guess I just figured the chances of a hungry shark picking my foot out over some bait fish were basically nil. A kid got his leg bit off (maybe it was his arm, I don't remember) last August here. I think I posted on this board about it. Anyways, the kid is slowly making progress last time I heard, at least showing some slight signs of being aware of his surroundings. That isn't want keeps me away from the beach though. It's the frickin' sun. I'm very fair skinned and I have been sunburned enough in my life.

as for movies that freaked me out... Alien freaked me out a lot more than Jaws did while watching it. I guess 4 year olds shouldn't watch Alien by themselves at night! Hell, Orca freaked me out a lot more than Jaws did. I think it was because I had been to Sea World, and those pretty killer whales were supposed to be kind and gentle. Then I watched Orca and the killer whale eats that guy... oops, instant nightmares. (I actually don't remember this directly, but my mom told me about it. I do remember having the dream about Jaws, but it ended nicely.) Nightmare on Elm Street gave me bad nightmares (I guess that was the point) for months after seeing it. Of course in the movies where they die for real when they die in their sleep doesn't help a kid's mentality about having nightmares. The dreams finally stopped for me when in one, I just got fed up of running from Freddie and waking up scared so I told him "go ahead and kill me!" He put the knives right between my eyes, everything went red in my dream, then black... then I woke up and was, of course, completely ok. Never had a scary dream about Nightmare on Elm Street again.
edit: oh yeah, I remember as a young kid at the beach here in Pensacola, that we had little tar and oil globules on the beach. It sucked stepping in them. I guess they might have come from the spill in Texas. I always figured they just came from offshore rigs. *shrug*
