When Gilman describes the colonial mansion, why does Gilman use the following diction:

"That spoils by ghostliness, I am afraid, but I don't care--there is something strange about the house--I can feel it"?

It foreshadows the narrator's imprisonment and obsession.

Answer:The most beautiful place! It is quite alone standing well back from the road, quite three miles from the village. It makes me think of English places that you read about, for there are hedges and walls and gates that lock, and lots of separate little houses for the gardeners and people.

There were greenhouses, too, but they are all broken now.

That spoils my ghostliness, I am afraid, but I don't care--there is something strange about the house--I can feel it.
