Why are dolls, teddy bears, etc. used as horror objects in horror films?
In many horror films, toys such as dolls, teddy bears, and puzzle boxes are used as objects which the spirits/ghosts use to scare people. Some examples would be Annabelle, the crooked man musical box from The Conjuring 2, Billy, Chucky, Jigsaw... Why are they used when there could be scarier objects like knives, guns, etc.?
