Carter's Grove Plantation is known for several haunting phenomena, including a phantom harp sound believed to be from regretful women who rejected proposals, unexplained gusts of wind, and the sense that spirits are aware of and interact with visitors. These phenomena are attributed to various historical events and occupants of the estate, though the site is no longer open to the public. A phantom harp is reportedly heard throughout the mansion, which some attribute to the spirits of women who regret turning down marriage proposals. Employees and visitors have reported feeling sudden, unexplained gusts of wind moving through the plantation's corridors. Some individuals have reported that spirits at Carter's Grove seemed aware of their presence and even commented on them, with one interaction involving 19th-century Civil War-era women.
