À propos de ce contenu audio
 Curious what really happens when the mind steps outside ordinary waking life?

This podcast explores the science, history, and culture of altered states — from psychedelics and plant medicines to meditation, hypnosis, anesthesia, dreaming, sensory deprivation, and everything in between.

We dig into the research without the jargon overload, unpack the stories and traditions that shaped these experiences across cultures and centuries, and talk honestly about what people actually encounter when consciousness shifts. No hype, no lectures — just clear, thoughtful conversations about one of the most fascinating (and least understood) parts of being human.New episodes regularly.

  • Are You Still Here? The Out-Of-Body Experience (What Is It?)

    Are You Still Here? The Out-Of-Body Experience (What Is It?)
    Oct 22 2026
    Out-of-body experiences, explained by neuroscience.

    Why does the brain sometimes make you feel like you're floating above your body?

    In this episode of Altered, I look at brain stimulation cases, the temporoparietal junction, virtual reality body illusions, fighter pilot G-LOC, sleep paralysis, ketamine, and near-death reports.

    It starts with a 2002 case published in Nature, where a gentle electrical pulse to one spot in a woman's brain made her feel she was floating near the ceiling, looking down at her own legs.

    From there we ask a bigger question: what if the feeling of being inside your body is something your brain builds moment to moment, and what if it can come apart? I try to be fair to both sides.

    The skeptics have strong arguments, and some of the stories are genuinely hard to wave away. Have you ever had an out-of-body experience?

    Tell me about it in the comments. Stay curious, go out and do great things.

  • What Actually Happens When You Die? (The Final Minutes)

    What Actually Happens When You Die? (The Final Minutes)
    Oct 14 2026
    Examine the physiology of near-death experiences and how the brain reacts when oxygen supply is abruptly cut off.

    We explore the critical window of brain function when the heart stops, causing rapid depletion of fuel and oxygen. This analysis investigates the biological mechanisms at play during the moments of clinical death, moving past speculation to look at the high energy demands that sustain our cognitive processes. It is for those interested in the physiological reality of the dying process.

    By observing the relationship between cerebral metabolism and the cessation of vital signs, we can better grasp the limits of human consciousness. We break down the clinical sequence of events that occur as neural activity falters, providing a clearer picture of what happens at the boundary of life. This inquiry bridges the gap between medical reality and the subjective accounts often reported during these critical moments.

  • Ibogaine: Everything You Need to Know About the Pros and Cons

    Ibogaine: Everything You Need to Know About the Pros and Cons
    Oct 6 2026
    Opioid withdrawal symptoms may be significantly reduced by a compound derived from a traditional, yet dangerous, root. This substance, a potent rainforest shrub root, has been used in ceremonial contexts for centuries.

    We examine the intersection of these botanical compounds and modern medical inquiry to understand how this root interacts with the human body. By analyzing the evidence from recent clinical trials, we look at the potential for therapeutic application and the inherent risks of such a treatment.

    This inquiry is for those interested in the relationship between historical plant knowledge and the physiological reality of addiction. We also consider the nature of opioid withdrawal when viewed through the lens of modern pharmacology.
