Trance states, found across cultures from shamanic rituals to contemporary practices, are increasingly studied by researchers and clinicians. This review describes their common phenomenological features, such as altered awareness and perception. Using advanced neuroscientific techniques, it reports on the neural mechanisms underlying these states, including changes in brain connectivity and dynamics. The review also examines clinical applications, suggesting that trance states may be useful in therapeutic settings. By connecting subjective experience, brain function, and practical use, it advances understanding of trance and its potential benefits.
Shamanic trances are non-pathological altered states of consciousness that differ from normal waking states in phenomenology and neurophysiology. A review of 27 studies classified findings into four dimensions: phenomenology, psychology, neuro-physiological functions, and clinical applications. The trances are influenced by multiple personal and environmental variables and may offer therapeutic potential, but the evidence is preliminary and requires rigorous studies to assess effectiveness for complementary therapies. The review highlights shamanic trance as a multifaceted area of study at the intersections of consciousness, spirituality, and therapy.
