We know about haunted houses, asylums, hospitals, hotels, castles, and other buildings, but nature has its own legends of horror that scare people even today. Forests can be scary even without ghost stories attached to them, and sometimes it's even a single tree that is said to be haunted, like the haunted apple tree in Douglass, Massachusetts.
Legend says that, in the 1800s, a traveling peddler stopped to rest under this apple tree, and someone—likely the orchard owner himself—slashed the peddler’s throat and killed him. The victim’s spirit haunted the murderer, following him everywhere, until the man moved away to escape it. Passersby later reported seeing apparition standing under the apple tree, holding its throat and crying shrilly. The flesh of the apples grown on this tree are stained red, reminiscent of the blood that gushed from the peddler’s neck.
