How does the speaker hang his attitude?

‘The Shed’ is a mysterious poem. In the first three stanzas the speaker seems to be scared of the shed. He thinks that there is a ghost in the shed. He thinks that the strange voices are mysteriously staring at him. He believed in the ghost stories. However, in the final stanza, there is major change in the speaker’s attitude, regarding the shed. Now he has come to know, that all these ghost stories were unreal stories told to him, and that they have nothing to do in the world of reality. And therefore, he determines that he will enter the shed without any fear of ghosts.
