Well, when I read poetry I can’t imagine that what’s in the reader’s head is ever what was in the poet’s head, because there’s usually very little in the poet’s head.
You mean . . .
I mean, I think the reality of the poem is a very ghostly one. It doesn’t try for the kind of concreteness that fiction tries for. It doesn’t ask you to imagine a place in detail; it suggests, it suggests, it suggests again.
