I went through a phase from preteen to early adult when I watched scary horror movies, and read scary horror movies. Yes, they do bother me, and I found over time that I really didn't like them, so I rarely watch such any more. I still like some of the old monster movies and I like a lot of sci fi stuff, too, but you can keep the horror movies.
I do think that Bela Lugosi was a great Dracula. I also saw Jack Palance in that role once, and he was really good doing Dracula, too. I basically grew up with Peter Cushing, Christopher Lee, Boris Karloff, Peter Lorre, Vincent Price, and many other great old horror stars.
The Monster movies aren't really that scary because the monsters are so fake, but I like to watch those movies to see old stars I like, and not just the horror stars. Many other stars co starred in these movies, so I get to see them, too.
I've been into the outer space type sci fi since I was about 10 years old, That's over 4 decades of blast offs.
I am really not into the creepy horror stuff any more, though. And yes, it has occasionally caused nightmares, so I will stick to the sci fi, and you can have the horror stuff.
