Here are some that I can think of.

-The Babadook

-The Grey (I'm not sure if this counts as a horror movie but it is often categorized as one and it could pass as one)

-The Descent

-The Thing (1982 version of course)

-Rosemary's Baby

-Grave Encounters (the original)

-Insidious (all movies in the series)

-The Cabin in the Woods
