Mindfulness training can lead individuals to experience altered states of consciousness, such as disembodiment and unity, as outlined in a recent study by researchers at the University of Cambridge.
While these experiences can have positive effects, it’s important to note that they may not always be pleasant. Both mindfulness teachers and students should recognize that these states can be a byproduct of the training, and students should feel comfortable discussing any concerns with their teacher or healthcare provider.
In recent years, mindfulness-based programs have gained popularity, with approximately 15% of UK adults having engaged in some form of mindfulness practice. Often used to reduce stress or manage conditions like depression and anxiety, mindfulness has been noted anecdotally to lead to changes in perception and self-awareness, sometimes resembling effects of psychedelic substances.
From September 2015 to January 2016, a randomized controlled trial conducted at the University of Cambridge assessed the effectiveness of mindfulness training in helping students cope with exam stress, highlighting its potential in supporting those at risk of mental health issues.
Dr. Julieta Galante from the University of Cambridge’s Department of Psychiatry spearheaded the trial and notes the challenges in determining whether altered states of consciousness result from mindfulness practice or if individuals predisposed to such experiences are more likely to engage in mindfulness activities.
The study followed up with participants a year later to explore reported altered states of consciousness, with results published in PLOS ONE.
Participants were surveyed on 11 dimensions, including spiritual experiences, blissful states, disembodiment, and unity. Among those who completed the questionnaire, individuals who received mindfulness training were twice as likely to report experiences of unity and disembodiment compared to the control group.
Furthermore, a correlation was found between hours of formal mindfulness practice and the likelihood of experiencing altered states, with those practicing more regularly more inclined to report unity, disembodiment, or blissful states.
During a sub-sample analysis, a significant number of participants who meditated revealed experiencing altered states during their sessions, with some reporting unity, blissful states, disembodiment, and insightfulness experiences.
Dr. Galante acknowledges her own experiences with altered states of consciousness as a mindfulness practitioner, underscoring the importance of open discussions between teachers and students about such encounters.
While many altered states may be enjoyable, some individuals may find them unsettling. Dr. Galante stresses the significance of acknowledging and appropriately addressing these experiences within the context of mindfulness training.
The research received support from the University of Cambridge Vice-Chancellor’s Endowment Fund, the University Counselling Service, and the National Institute for Health Research (NIHR) Applied Research Collaboration East of England program.
