I would definitely recommend checking out “The Babadook” and “Oculus.” Glad to see “Sinister” near the top of your list, as it is one of my favorite horror films. By “Blair Witch” do you mean the new “Blair Witch” or the original “Blair Witch Project?” I happen to really enjoy “The Blair Witch Project,” but it did lose some of its magic when it was revealed that the events portrayed were not real.
Updated: I watched .found which was on my list of things to watch again. It's off the list now, put it that way.
