It is important to understand the difference between religious experiences, such as power animals, visions, and spirit contact in shamanism, and the symptoms of mental illness, even though they may superficially seem similar. At times, the shamanic practitioner is met with questions about this, including from healthcare professionals. In this article, we therefore attempt to explain the difference. Research has provided insight into how religious experiences, especially within shamanic traditions, are often culturally conditioned and deliberately sought out, while mental illnesses such as schizophrenia and other psychotic disorders are often involuntary and disrupt a person's ability to function normally. Scientifically, it is also possible to distinguish between these experiences. It is important to bear in mind that this article is written from a scientific standpoint and that, for example, in traditional shamanism one may have entirely different views on this.
Cultural context and intention Shamanic experiences such as visions, power animals, and spirit contact are central elements within a structured and cultural framework. Shamans deliberately seek out these experiences through rituals, often in connection with healing, guidance, or spiritual insight. This is an active process in which the shaman uses specific techniques such as drum journeys, fasting, or meditation to attain an altered state of consciousness. Such experiences are recognized and validated by society as a normal part of spiritual practice.
By contrast, mental disorders such as schizophrenia are often characterized by involuntary, disruptive symptoms, including hallucinations and delusions that lack a cultural framework. These symptoms can arise without intention, and they are usually not considered meaningful by the person or the surrounding society. According to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), a key factor in diagnosing mental disorders is the degree of impairment the person experiences, which is rarely the case for shamans within their culture.
In his book Shamanism: The Neural Ecology of Consciousness and Healing, Michael Winkelman points out that shamanic practices are universal phenomena in human societies and function as a form of ritualized, controllable experience. These experiences differ significantly from pathological conditions in that they are integrated into cultural rituals that have health-related, therapeutic, or spiritual purposes (Winkelman, 2000).
Control over the experience Shamans often have a high degree of control over their visions and spiritual experiences. They can begin, direct, and end a spirit journey through the use of particular rituals and techniques. This is another important difference from mental illnesses, where hallucinations and delusions are usually beyond the person's control and can be frightening or disturbing.
When a shaman makes contact with spirits or sees power animals, it is within an understanding that there is a purpose or meaning behind the experience. This often takes place within safe boundaries and with an understanding that the experience serves to help or guide. For people with mental disorders, hallucinations are often chaotic, confusing, and impair their ability to distinguish between reality and illusion.
Anthony Wallace, an anthropologist who has studied religious experiences and their relationship to mental health, has pointed out that in shamanic cultures these experiences are recognized not only as normal, but as healing tools for both the individual and the community (Wallace, 1966). This indicates that shamanic experiences are under control and serve a functional role, in contrast to the uncontrolled symptoms of mental illness.
Neurobiological differences Neurological research has shown that shamanic trance states and hallucinations related to mental illnesses involve different parts of the brain. When shamans enter trance states, a synchronization occurs between brain waves, especially theta and alpha waves, creating a calm, meditation-like state characterized by focused awareness. This is a controlled change in consciousness, often achieved through specific techniques such as drumming or chanting.
In mental illness such as schizophrenia, by contrast, brain activity is often dysregulated. Imbalances in the dopamine and glutamate systems have been demonstrated, leading to unpredictable hallucinations and delusions. These changes occur without the person's control and often lead to disrupted thinking and behavior.
Research by Michael Persinger and others in the field of neurotheology has explored how specific brain wave changes during controlled religious experiences, including shamanic rituals, differ from dysfunctional brain processes in mental illness. Persinger concluded that certain controlled spiritual experiences can have a health-related and healing effect, which stands in contrast to the chaotic experiences of mental illness (Persinger, 1987).
Personal and social functioning Religious experiences in shamanism have a positive function in the life of both the individual and society. The shaman often serves as a guide, healer, and spiritual leader, and his or her experiences are regarded as valuable by society. Shamans usually maintain a high level of social functioning and play an active role in the community. Their spiritual experiences are integrated into their daily lives and are recognized as legitimate and meaningful.
Mental disorders, on the other hand, often lead to reduced functioning both socially and personally. Hallucinations or delusions can impair a person's ability to work, maintain social relationships, or take care of themselves. This is a central diagnostic criterion in psychiatry, where the degree of impaired functioning is used to distinguish between mental illness and normal variations in human experience.
The psychiatrist Stanislav Grof has advanced the understanding of spiritual experiences as part of human consciousness development, and has emphasized that such experiences can be health-promoting rather than pathological, depending on the context in which they arise (Grof, 1985). This perspective supports the view that shamanic experiences are not an expression of illness, but a natural part of human spirituality.
Although religious experiences within shamanism, such as visions, spirit contact, and power animals, may seem similar to the symptoms of mental illness, there are significant differences between them. Shamanic experiences are culturally contextual, deliberately induced, and experienced as meaningful both for the individual and for society. Mental illness, by contrast, is characterized by involuntary, chaotic symptoms that often disrupt the individual's daily functioning. Research in neurology, cultural anthropology, and consciousness supports the idea that shamanic experiences are not pathological, but part of the human being's natural capacity to explore consciousness and spirituality.
