Understanding Wuthering Heights symbolism provides depth to Emily Bronte's classic.
Ghosts - The inhabitants of Wuthering Heights and Thrushcross Grange are haunted by past events. Heathcliff craves the past and longs for the ghost of Catherine to haunt him. Lockwood, during the first few days of his residence, is awakened by Catherine's ghost as he slumbers at Wuthering Heights. It is apparent that Lockwood will be imposed upon by the abnormal goings on of the Heights and Thrushcross Grange. At the end of the novel, rumors persist that both Heathcliff and Catherine's ghosts roam the moors at night. Although the veracity of such events remain ambiguous, there is no doubt Heathcliff's life has made an impact on the still living.
Weather - The extreme winds prevalent at the Heights symbolize the hardness of the inhabitants. At Thrushcross Grange, things are much more delicate and mild, like its initial inhabitants, the Lintons. Wind and rain are present when Mr. Earnshaw dies, when Heathcliff departs from Wuthering Heights, and when Heathcliff dies.
