Get into short horror stories. GOOD stories published by professional magazines like Nightmare, The Dark, Black Static, Weird Horror, Pseudopod. Those are all places that pay professional rates and who have won tons of awards. Anthologies edited by Ellen Datlow are also good, who does the Year’s Best. Crystal Lake Publishing is good as well, both their short stories, novels, and their podcasts. Weird Little Worlds is another indie publisher that has put out good stuff. (Disclosure: I’ve had stories published by both CLP and WLW—the Mother: Tales of Love and Terror antho I was in was a finalist for the Bram Stoker award this year.)

If you want good horror, you need to go to the places that publish it professionally. Issues are pretty cheap, and there’s plenty of free stuff on their sites as well.
