The oak-paneled bed is the piece of furniture which is the symbolic center of Wuthering Heights – both the novel and the house – and provides the setting for two of the novel’s most dramatic events. Lockwood, the narrator, who first finds refuge in the bed, increasingly starts having nightmares. As he later finds out, the bed was Catherine’s and it was her sacred place as a retreat from everyone. His nightmares suggest that Heathcliff is angry with Lockwood because he is sleeping in Catherine’s bed.
Later, the supernatural powers that surround the bed become more intense when Heathcliff dies there, transforming the bed into a kind of symbol of a coffin where Heathcliff is finally “reunited” with his love. Where Lockwood tried to keep the bed’s window closed, Heathcliff is found dead with the window wide open, almost as though his spirit has escaped.
