Midsommar is one of my favorites, or you could try It Follows if you haven't seen either of those. Midsommar is a slow burn intrigue sort of thing, but quite realistic, most of the most horrifying things about it could happen to you for real.
It Follows is a very creative movie, very much about the fear of being chased by an entity that never stops, extremely interesting premise
Same director, probably what you're feeling there is a sum of little touches. I liked the first half of Hereditary quite a bit, didn't really like where it ended up, got too fantastical for my tastes, I like pulp horror too, but I really really like horror that's plausible
