The quote reflects a surprising twist in the typical expectations of an alien invasion. Traditionally, many assume that extraterrestrial beings must be tangible and living to pose a threat. However, the mention of ghostly invaders introduces an eerie and unexpected element that challenges conventional ideas about life forms and their potential to invade Earth.

Stephen King's "The Tommyknockers" plays with the notion of an invasion that transcends biological life. By suggesting that even imagined scenarios, such as an invasion of ghosts, can be potent and disconcerting, King explores themes of fear and the unknown, making readers reconsider their assumptions about alien encounters and the nature of existence.
