(Horrifying Trope) Beings that can limit or restrict perceptions
Monsters (Something is Killing the Children) are physical embodiments of fear formed out of human fear and myths, they feast upon those that made them and, mainly, live for destruction and chaos, though there are some exceptions. Only children are able to see the monsters, and thus are the monsters’ first targets and victims.
It (Stephen King’s IT) can limit the perception of the citizens of the town of Derry to a certain extent, but it’s much harder for children, as they still hold onto some pieces of hope. He can limit empathy and even what a person might see in front of them, but only if IT allows it to happen and if it serves to please IT.
