Alderson-Day tackles the notion of presences around us, unseen, but not necessarily unheard. Is hearing voices a sign of mental illness or a signal that someone or something else is near? Drawing on cases, current, historical, and in some cases, famous, the author presents a fascinating argument about mental illness vs. the paranormal

This is a really interesting book especially for a psychology student. The author not only includes scientific facts and research he includes stories from patients. It’s not your typical nonfiction boring book this one is actually interesting.
