There's such a plethora of stories here, that it's truly a mixed bag. If you're into more psychological stuff, I recently put a story out that may kinda fit the bill. You can find it here.

I have a few that I've written myself that fall into the realm of psychological horror, but I've read some great ones on this wiki. This one is a little more existential, but I thoroughly enjoyed the concept of "torment" in it.

The reality and theory categories are good for if you want a story to leave you "pondering".

Honestly, I got terrified by whatever you call a movie advertisement on TV for IT (i was pretty young) and I would just feel like something was hiding and that it was gonna ambush me if I wasn't on high alert

Find a story like that and be in the perfect enviormont (how do you spell that lol)

I really wouldn’t use NoEnd House as a good example of psychological horror. But as others have pointed out, try Genre tag surfing.

I can relate. I noted out before the 5-minute mark but can handle a story about a child being skinned alive by a giant.
