Since one event in From Darkness Spellbound occurs in 1816 I thought I'd post some information regarding the surge in interest and experiences of what we often call the supernatural in the 1800s.

Updated December 07, 2017"The 19th century is generally remembered as a time of science and technology, when the ideas of Charles Darwin and the telegraph of Samuel Morse changed the world forever.
Yet in a century seemingly built on reason there arose a profound interest in the supernatural. Even a new technology was coupled with the public's interest in ghosts as "spirit photographs," clever fakes created by using double exposures, became popular novelty items.
Perhaps the 19th-century fascination with the otherworldly was a way to hold on to a superstitious past. Or perhaps some really weird things were actually happening and people simply recorded them accurately.
The 1800s spawned countless tales of ghosts and spirits and spooky events. Some of them, like legends of silent ghost trains gliding past startled witnesses on dark nights, were so common that it's impossible to pinpoint where or when the stories began. And it seems that every place on earth has some version of a 19th-century ghost story." https://www.thoughtco.com
