I'm very happy you noticed the connection! Hopefully I wasn't so spot on it seemed derivative. I like the concept of a force that is really too ancient and powerful to defeat. It's not just that it is more frightening, but that it can be seen as an representation of the most oppresive of human emotions. Kids may eventually convince themselves that there is no one under the bed, only to graduate to adolescence where they feel nobody likes them and no one ever will. Loneliness, depresssion, paranioa and related feelings are common and sometimes blossom into real diseases. The cures are often limited and the sensations are always there. You cannot get away by just not going into a certain room. You are the one who is haunted. So we don't quite vanquish the monster we cope.
