Have you ever experienced Auditory Hallucinations? I haven't so far, but here is some information about people who do. More here. https://www.seeker.com/health/mind/heres-why-some-people-experience-auditory-hallucinations
A team of Yale researchers tapped local Connecticut psychics for a novel study into why some people hear voices — with results suggesting future avenues for research into treating hallucinations among schizophrenics.
In the process, they also managed to develop a technique for inducing hallucinations, even in mentally healthy people.
Researchers Phillip Corlett and Albert Powers wanted to locate subjects who hear voices but experience no other psychotic symptoms. To do so, they turned to local community of psychics near Yale University through an organization representing regional clairvoyants and sought out people who report hearing voices — including those who believe they’re hearing spirit guides, dead relatives, guardian angels, or other ethereal beings.
For example, one of their subjects, a middle-aged woman who works as a police dispatcher, said she occasionally hears a voice that gives her innocuous, helpful advice, such as which direction to turn in traffic.
In fact, studies indicate that at least 4 percent of the general population report hearing voices at some point in their lives, even those who show no other symptoms of mental illness. That’s significantly more than the 1 percent of the global population thought to suffer from schizophrenia, which doesn’t always involve auditory hallucinations.
