What do you mean what does it do? I don't know. I do know that when I moved in a little over a year ago that there were triple 6 stickers ev where.I think a satanic person lived here!I'm finding this wierd b/c I've never had this kinda thing happen.Only other clue I have is my dog looks into the hallway every now and then and growls and snarls and looks up like she's looking at a person and she won't let up.Sorry couldn't funmail ou I think I reached m limmit for now.BTW I'm not terrified just a little scared.
