"The Apparition" by John Donne - Imagery

"Then shall my ghost come to they bed." This poem is particularly full of imagery. The whole description is the speaker as a ghost coming back to haunt his lover. The descriptions display the speaker's dismay with his lover. She won't have sex with him yet and it's killing him. He says that when he comes back from death, he will haunt her like a ghost. He also says he doesn't want to give away what he's going to say now because he'd rather have her repent than be innocent. I see that as harsh. He would rather her do what she is doing and then torture her than ask her to do his desires and never haunt her. The imagery of this poem sets a tone of dark, haunting death.
