Altered States Unlocked
Bottom line: Various practices inducing altered states of consciousness may suggest shared mechanisms involving brainwave changes, ego dissolution, and neuroplasticity, with some showing association with reduced symptoms of mental health conditions.
Somewhere in the world, a person is undergoing a Life Between Lives hypnotherapy session, convinced they’re accessing memories from past lives. Another is using psilocybin to treat depression. A third is practicing mindfulness to reduce anxiety. What do these diverse practices have in common? They all induce altered states of consciousness (ASC), a universal human capacity to access and transform the subconscious mind. But how do they work, and what do they reveal about the nature of consciousness?

The Diverse Landscape of ASC
The review draws from over 25 disciplines, grouped into five clusters: contemplative and meditative practices, breathwork and somatic practices, plant-based and psychedelic practices, ritual and cultural practices, and neurotechnology and sensory modulation. This broad scope shows common mechanisms across all these fields—like suppression of the default mode network, autonomic nervous system regulation, and enhanced neuroplasticity.
Mindfulness-based interventions can reduce symptoms of depression and anxiety by 30 to 40% in a few weeks. Psilocybin therapy has been shown in multiple randomized controlled trials to reduce symptoms of treatment-resistant depression by 60 to 70%.
The Neurobiological Mechanisms
Comparing the neurobiological effects of different ASC practices reveals a common pattern: they all temporarily suspend ordinary critical consciousness to allow access to subconscious patterns. This happens through mechanisms like theta and alpha brainwave entrainment, ego dissolution, and interoceptive predictive coding.
Research on neurofeedback has shown it can increase brain-derived neurotrophic factor (BDNF) by 20 to 30%, leading to better cognitive function and reduced symptoms of anxiety and depression. Psychedelic-assisted therapy has also been found to increase vagal tone and heart rate variability, which can improve emotional regulation and reduce PTSD symptoms.
Clinical Applications and Evidence
The strongest clinical support comes from MDMA-assisted therapy for PTSD, psilocybin therapy for treatment-resistant depression, EMDR for trauma, and mindfulness-based interventions for depression relapse prevention and anxiety. Neurofeedback also shows promise for ADHD and anxiety disorders.
Transpersonal practices like Life Between Lives hypnotherapy show some preliminary evidence for treating existential distress, grief, depression, and life-purpose confusion. A case series study found that 80% of participants reported significant reductions in anxiety and depression. A review of neurofeedback for ADHD found it can reduce symptoms by 30 to 50% in a few months.
Philosophical Frameworks and the Subconscious Mind
Philosophical traditions—Vedantic, Buddhist, Jungian, Platonic, transpersonal, and neuroscientific—all offer different ways to understand the subconscious mind as the target of ASC practices. These frameworks agree that the subconscious holds conditioned patterns, unconscious complexes, and predictive priors that can be accessed and transformed.
In Vedanta, these patterns are called samskaras. In Buddhism, they’re referred to as alaya-vijnana—a repository of memories and experiences.
Frequently Asked Questions
-
What is the difference between altered states of consciousness and ordinary consciousness? Altered states of consciousness refer to experiences that differ from ordinary waking consciousness, such as meditation, psychedelic experiences, and dream states.
-
Can ASC disciplines be used to treat mental health conditions? Yes, clinical evidence shows strongest support for MDMA-assisted therapy in PTSD, psilocybin therapy in treatment-resistant depression, and mindfulness-based interventions for depression relapse prevention and anxiety.
-
What is the role of the subconscious mind in ASC disciplines? The subconscious mind is seen as the universal therapeutic target—a place where conditioned patterns, unconscious complexes, and predictive priors can be accessed and transformed.
-
How do ASC disciplines converge on temporarily suspending ordinary critical consciousness? They do this through mechanisms like theta and alpha brainwave entrainment, ego dissolution, and interoceptive predictive coding.
-
What are the potential risks and benefits of using ASC disciplines? Benefits may include reduced anxiety and depression, improved emotional regulation, and a greater sense of purpose. Risks can include increased anxiety, emotional distress, and unpredictable outcomes.
