Hey, I'll bring it back, then.
A low-budget but chilling psychological/vampire movie is Let's Scare Jessica To Death. No, there are no CGI (it was filmed in 1971) and not even any fangs. It's the mood that makes it creepy. Even the 'vampirism' or anything supernatural is a bit in question. It's fairly realistic, though, with the main characters, hippie-types, moving into an old farm house in a rural, closed comminuty in Connecticut. They meet a young drifter hiding in the house and invite her to stay with them. If the pace is slow, that's offset if you watch it late at night, alone, with the lights out.
