Bookish people, who are often maladroit people, persist in thinking they can master any subtlety so long as it's been shaped into acceptable expository prose.
Atmosphere, not action, is the great desideratum of weird fiction. Indeed, all that a wonder story can ever be is a vivid picture of a certain type of human mood. The moment it tries to be anything else it becomes cheap, puerile, and unconvincing.

Avoid bald catalogues of incredible happenings which can have no substance or meaning apart from a sustaining cloud of colour and symbolism.
