So for me, I'm not really into horror and get scared easily. I avoided Barnes and Noble for years cause I saw a scary movie cover. Also, had the misfortune as a young child to be afraid of my bathtubs, which got me to take showers instead. I saw this movie trailer on TV one day, and I barely remember it, but all I remember is that showed a guy taking a shower, and this woman in a "hidden like environment" is watching him on a monitor. But then the guy taking a shower starts screaming in agonizing pain, and she smiles as she sees this. Then I think the final part of the trailer was of something bad happening to a lady taking a bath in a bathtub, but yeah I'm not the best with horror, especially anything with creepy clowns and dolls.
However, I do know about horror movies, you see on YouTube I watched horror movie reviews from a youtuber named Phelan Porteous, or just Phelous for short. I haven't watched his horror reviews in awhile, but I just like learning. I loved learning that there is a horror thanksgiving movie with a killer turkey...yes that's a real movie and it's really stupid. I will never watch it, but it was fun watching Phelous making fun of the movie. Also, I like to tease movies that get too many sequels with saying: "Well, I guess they are going to space now", cause Phelous made a joke about Jason going to space, had to look it up if it was real and yep, he does in the 10th movie, and I just find that so incredibly funny, lol
I'm actually more familiar with horror anime, and the one that was any good, is called "When they Cry" in English (The Japanese name is so much better). It has a cool steup, because it's based off a sound novel (Like a visual novel, but their is more focus being put into the sounds) and it has "mini-arcs". Basically, the group of characters start off happy, someone goes insane and they die. But when a new arc starts, everything is resets, they don't remember what happen in the last arc, so it's like "Groundhog day (Haven't seen the movie, but I know about the whole "time resetting thing") inspired horror setup". So while I like the setup, I watched this a long time ago before I came to know Jesus as my savior. This show is great horror, but it does touch upon iffy stuff I think most people on here wouldn't like the concept of "being spirited away" in the show and it's roots deep in Japanese mythology and culture. Plus this show can get pretty gruesome and bloody. I've seen other horror anime, but this is the only one I remember ever liking a lot, probably because it was the perfect fit for my "edgy high school self", lol.
But yeah that's about as much knowledge I have on horror, Phelous's horror reviews from what I remember are pretty great, but he does bad language here and there sometimes, so leaving that as a warning if anyone wanted to check out his horror reviews.
Edit: I forgot to mention for videogames, definitely know about horror games, but haven't played any.
