Which movie gave you childhood nightmares?

I'm sure everyone has a childhood memory of some movie that gave them nightmares. Mines was Robocop 2...I still blame it for the one movie that scared me away from anything robot-like. Before that movie, my favorite films were Robocop, Short Circuit, and theTerminator. I loved watching cartoons like Go-Bots and Transformers. Anything mechanical I loved...until my parents took me to see this movie. It must have been the Drug aspects of Robocop 2 that really scared me as a child. I also blame that movie as the reason I was scared away from Drugs while growing up, it scarred me!. Awwww 2 Bad.
