From The Arthur Conan Doyle Encyclopedia
Haunting Dreams: A Symposium of Eminent Men is a selection of opinions from various authors like Sir Oliver Lodge, Bernard Shaw... and including Arthur Conan Doyle asked about their "recurring dreams", published in The Strand Magazine in february 1923.
Below is only shown the Arthur Conan Doyle opinion:
SIR ARTHUR CONAN DOYLE,
who, like "W. W.," needs no introduction to STRAND readers, says that he has never had a recurring dream. "But," he adds, "I have several times had prophetic dreams, exact in detail. In sleep the soul is freed and has enlarged knowledge. This it endeavours to pass on to the body, but it seldom succeeds. When it does, it is just at the moment between sleeping and waking."
