Charles Dickens, Sir Arthur Conan Doyle, W. B. Yeats were members of The Ghost Club, founded in London in 1862, by people who took ghosts seriously

In a recent post, I noted that Franz Kafka believed in ghosts, based on his own personal experience, but you might have dismissed that fact, since, judging by the things he wrote, Kafka must have been weird.

So you might be surprised to learn that Sir Arthur Conan Doyle, creator of no-nonsense Sherlock Holmes, believed in ghosts, too. And so did Charles Dickens and W. B. Yeats.
