As a kid I always loved the 90s show 'Are You Afraid of the Dark?' and, though it's really more fantasy than horror, the show 'Buffy the Vampire Slayer.'
I'm sure you've already read most of my favorites, if your profile picture is to be believed, but I think 'Tell-Tale Heart' is one of the best stories I have ever read. 'The Fall of the House of Usher' is another good one, as is 'The Cask of Amontillado.'
As far as movies go, Silence of the Lambs is brilliantly executed, though none of these may be the traditional horror that you might be looking for. Hope they help anyway!
