Vampire lore question.
Does a vampire require the resident of a home to invite them in? I see it in this movie, I see it in "Let the right one in" and "Let me in." It is as if something bad will happen to the vampire if the resident doesn't specifically say "Please come in" or something like that. A gesture, like opening a door, isn't sufficient.
Just wondering...
