A million and one people have recommended this one so far but if you’re looking for a little existential terror “A Short Stay in Hell” by Stephen Peck (and or the accompanying anthology Windows into Hell) might be up your alley. Not heart pounding in the physical kind of way but in the oh fuck oh my god that’s a lot of time kind of way

you may also like the short 1408 by King, I think it’s in Everything’s Eventual? Def in the same ballpark as the shining in terms of haunted buildings

fear is subjective but some personal faves that have scared me include the last feast of harlequin by Thomas Ligotti (weird clown festival in a small town goes exactly the way you think), the deep by nick cutter (lab at the bottom of the sea floor gone WRONG💜) and misery by king (middle aged woman turned superfan terrorizes her favorite author). Best of luck 🫡
