Scary Movie?

Night of the living dead

The fall of the house of usher

Jaws

and when I was a little kid my dad took me and my brother to see Night of the Grizzly.
Scared the crap out of me, I used to have nightmares about bears chasing me and I could barely run, legs felt like led, I would always wake up just at the bear caught up to me.
To this day, I'm really scared of bears.
