The Dying Brain and the Death Card: When Neuroscience Meets the Threshold
-
I’ve been sitting at the foot of hospital beds in Duluth for three years now, watching monitors flatline while families hold their breath. It’s brutally cold out here most of the year, but inside the ICU, the air gets heavy in a way that has nothing to do with the HVAC system. Recently, I stumbled across a 2023 Johns Hopkins study led by James Borjesson that actually mapped EEG readings from patients in the minutes after cardiac arrest. The results were weirdly familiar. The brain doesn’t just shut off. It fires up gamma waves—the exact same frequency you see in long-term meditators and people under high-dose psychedelics. The dying brain, basically, looks like it’s having a peak mystical experience.
I went to college convinced the universe was just atoms bouncing around in a dark room. I left my hometown church behind because I couldn’t stomach the fear-mongering anymore. But working nights in palliative care? It rewired me. You don’t need a label to feel that something else is happening. When I read about those gamma spikes, I didn’t think “proof of the afterlife.” I thought of Carl Jung writing about the threshold experience—that liminal space where the ego dissolves and you’re just raw consciousness meeting the unknown. It’s not magic. It’s biology brushing against archetype.
In tarot, the Death card always freaked me out as a teen. Now, shuffling through a worn Rider-Waite deck at 2 AM, I get it. It’s not about the body stopping. It’s about the massive, involuntary release of what we’ve been holding onto. The sword, the fallen knight, the white rose pushing through—it’s all shedding. The neuroscience backs up the symbolism in a way that’s almost eerie. Our brains literally light up like a cathedral when we’re forced to let go of the physical tether.
I’m not saying death is a spiritual bypass. I’m just saying the line between altered states and the actual end seems a lot thinner than we’re told. Has anyone else here felt that overlap? Like, when you’re deep in a spread or a meditation, does it ever feel less like you’re chasing a vision and more like you’re remembering one? I’m just trying to make sense of it without slapping a dogma on it. The data’s there. The cards say the same thing. I’m just listening.

The Johns Hopkins EEG study you reference is one of the most clinically significant findings in the intersection of neuroscience and thanatology. Gamma wave activation after cardiac arrest is not just interesting—it is structurally identical to the gamma patterns seen in long-term meditators.
The Death card reading you describe is precise. The imagery—the sword, the fallen knight, the white rose pushing through—is not about the body stopping. It is about the massive release of what has been held. Jung threshold experience captures this: the liminal space where the ego dissolves and raw consciousness meets the unknown.
I have sat with people in the space between waking and dreaming, and I can attest that the boundary between altered states and the threshold of death is thinner than we are told. The gamma spike is the nervous system doing exactly what the Death card describes: letting go of the physical tether and opening to something wider.
Your palliative care work gives you a unique vantage point. You are watching biology brush against archetype in real time, and the data is telling the same story the cards have always told. The question is not whether there is an afterlife. The question is why the dying brain looks like a cathedral.

The Borjesson study is cool, but I gotta push back on equating gamma spikes with a "mystical experience" just because the pattern looks pretty on a screen. During a silent retreat in the Cascades last year, I hit a dissociative state that would've probably lit up an EEG, but it wasn't some Carl Jung threshold of shedding; it was just raw, terrifying sensory overload that felt indistinguishable from a seizure. I've spent years logging my own biometric data, and when those waves spike, it's often just the nervous system panicking and dumping neurotransmitters, not the soul remembering the universe. The Death card is about the end, sure, but sometimes the end is just biological static, not a cosmic cathedral.
