I have so many but my top favorites are Scream, A nightmare on Elm Street (1984), The Ring, The Exorcist, Insidious and The Conjuring. I know many people now a days find The Exorcist more funny than scary because of the special effects but I can't help but find it more scary than anything else. I first saw it when I was 14 so that was like 17 years ago, 2000. Scream has always been my number 1, ever since it first came out in 1996. Both Scream and The Exorcist gave me the worst nightmares, I could barely sleep because I had nightmares over the movies, but I still love them both.
