Is Hearing Voices Ever Normal? Understanding Non-Pathological Auditory Hallucinations

The episode challenges the common misconception that hearing voices (auditory hallucinations) is exclusively a symptom of psychosis. Dr. Tracey Marks, a psychiatrist, clarifies that while voice-hearing can indeed be part of severe mental illnesses like schizophrenia or schizoaffective disorder, or associated with medical conditions such as intoxication, delirium, migraines, or seizures, it can also occur in individuals with no underlying psychiatric or medical problems. She precisely defines "hearing voices" as perceiving a voice or multiple voices as if someone is speaking, either externally or internally, distinct from imagination or internal monologue.

A significant body of research, including studies utilizing functional MRI to observe brain activation, supports the existence of non-pathological voice-hearing. Estimates suggest that 1-3% of the general population without psychiatric disorders experience this phenomenon. A 2017 study highlighted key differences between clinical and non-clinical voices: pathological voices tend to be more negative, frequent, distressing, and associated with a feeling of being controlled, often involving commands. In contrast, non-clinical voices are typically more positive, reassuring, and may include hearing deceased relatives or spiritual entities. These non-clinical experiences often begin earlier in life, in late childhood.

The podcast also delves into other non-pathological hallucinatory experiences, such as hypnagogic (falling asleep) and hypnopompic (waking up) hallucinations, which can be normal occurrences or signs of a sleep disorder if frequent. Dr. Marks distinguishes these from sleep paralysis, a frightening but harmless state where one is conscious but unable to move, often accompanied by hallucinations or a sense of presence, resulting from a disrupted REM sleep transition. While sleep paralysis can be linked to sleep disorders, stress, or irregular sleep schedules, it is not inherently dangerous.

Crucially, Dr. Marks provides practical guidance on when to seek professional help. She emphasizes that hearing voices alone does not necessitate psychiatric intervention unless it causes distress, such as hearing commands to harm oneself or others, or experiencing persistent negative commentary. However, if voice-hearing is accompanied by other symptoms like depression, or difficulties with thinking or communication, it may signal an underlying illness requiring evaluation. For support, she recommends self-help groups like the Hearing Voices Network, highlighting the importance of context and individual experience in understanding these phenomena.

"Is it ever normal to hear voices? Yes, and that's what I'm talking about today."

"In general, when we hear that someone is hearing voices, the knee jerk response is to believe that that person is experiencing a psychotic episode."

"Psychosis is a break from reality and not knowing what's real and what's not real."

"It's estimated that one to three percent of people with no psychiatric disorder hear voices."

"And what they saw was that the voices in the clinical group tended to be more negative, more frequent, and caused more distress."

"Non-clinical voices tended to be more positive and reassuring."

"If you have this experience of hearing voices, it doesn't mean you need to see a psychiatrist unless it causes distress for you."

"The things that people hear that cause distress are commands to do things, like harm yourself or others, hearing lots of negative commentary about yourself."

"Some studies have seen a high prevalence of people with childhood abuse experience this. And in this case, the association doesn't mean it causes voices. We can't draw that conclusion but it may mean that children who have experienced early trauma, especially repetitive trauma, may be more vulnerable to hearing voices and having the voices be a soothing mechanism of some kind."

"You should see a psychiatrist if you hear voices and have other problems like feeling depressed, or having trouble with your thinking or communication."
