Answer:
Supernatural events.
Step-by-step explanation:
Gothic literature, as it was developed during the 18th and 19th centuries, is a literary genre that combines horror, romance, fiction and a treatment of nature as if unexplored and full of hidden and dark potentials. This can clearly be seen in the fiction of Edgar Allan Poe or Mary Shelley, especially in her Frankenstein where it is precisely, the work of a doctor exploring the powers of life and nature that sets the reader in a peculiarly supernatural scenario.
