Episode 58: UFOlogy and ETs with Levi
2026/01/31
Try to keep your feet on the ground as we dive into UFOs, extraterrestrials, and all things paranormal! From primordial soup exobiology and ancient myths reimagined as alien encounters to Buddhist world-systems and Crowley's cosmic pen pals, we're exploring how spirituality and UFO lore shift through time. We'll explore the paraUFOlogy debate, why some spirits absolutely aren't aliens (looking at you, Enochian angels), and how New Age UFO culture gave rise to starseeds, downloads, and a whole galaxy of grifters. Strap in and let us know if you believe in aliens by the end!

Episode 57: Cults vs The Occult
2025/10/03
Don’t drink the Kool-Aid just yet, we’ve got a new episode for you! This week we are diving into the world of cults. What defines them, how they intersect with the occult, and why high-control groups can be so hard to spot, especially on social media. From mystery cults of the ancient world to modern movements like Scientology, Jonestown, NXIVM, we unpack the psychology, power structures, and tactics that keep people hooked. Strap in as we talk about charismatic leaders, doomsday prophecies, brainwashing myths, and the BITE model.

Episode 56: Hypnosis
2025/08/30
You are getting very sleepy…listen to our voices…
Hopefully you haven’t fallen into a trance-induced hypnosis just yet as there is a new episode to listen to! This contentious episode explores both the history of hypnosis and its more modern understanding. There’s a surprising amount of science behind this favored Victorian party trick that also has roots in spiritual practices.
Strap in as we discuss magnets, mesmerism, MRIs, and…The Pope?

Episode 55: Science of Prayer Pt 2
2025/05/28
Welcome back to part 2 of our 'Science of Prayer' series! Back in April we discussed prayer with Aiden the VVitch, with a focus on the use of prayer in a variety of spiritual and occult settings. In this episode, the hosts tackle the science behind prayer, investigating the mechanisms behind how prayer affects our brains as well as the controversial fields of faith healing and whether prayer can benefit our health.

Episode 54: New Years Magic and Updates!
2025/03/16
Hello from Hanne, Fel and Astra! It's been quite the year and we're excited to get back into it.

Episode 53: Epigenetics!
2024/02/10
It's a science-heavy one this week, everyone! This week the hosts discuss the intriguing world of epigenetics, where nature and nurture collide. Can you change your DNA? What effect does the world have on our genetics, and on us as people? Does this have any spiritual consequences, as some people claim? Tune in this week to hear about the science behind epigenetics and our thoughts on how this somewhat contentious field has been appropriated by the spiritual world.

Episode 52: The Magnanimous Life of Dr. John Dee
2024/01/14
We are back with a long-awaited episode of our Occultists & Scientists series focusing on the life of John Dee and his scryer Edward Kelley. A renaissance man in every right, Dee was a physician, engineer, theologian, astronomer, cartographer, and magician - working with the angels to develop a unique system of angelic magic now described as Enochian. But this tale of the great magician has dark secrets…imprisoned for performing astrology, rumours of being a spy, hooking up with others wives, oh my! Perhaps like most magicians of his time, piousness was just a rumour. Join us as we soar to the skies and explore the magnanimous life of Dr. John Dee.

Episode 51: Prayer with Aiden the VVitch
2023/04/01
This week, TTAC are delighted to be joined by a special guest: Aiden aka @AidenTheVVitch In this episode, the hosts discuss all things prayer. How is prayer typically applied across different occult practices? Do you need to pray to be an occultist? Why are so many people ‘afraid’ of prayer? Is there any scientific evidence for prayer as a health intervention? And what’s the difference between prayer & spells, anyway? We hope you enjoyed this special guest episode of TTAC - let us know if you’d like to hear more from Aiden in the future!

Episode 50: Incense Oils and Perfumes
2023/03/12
In this episode, the hosts dive into the science of smell & the odiferous side of the occult Why is incense such a popular offering? Does an oil's odour reflect its properties? And what on earth does a saint smell like?! This episode features four case studies across different traditions to explore the seemingly-ubiquitous - but surprisingly diverse - role of fragrance in the occult. You can also expect to hear about science of smell & how odour can interplay with cognition.

Episode 49: Conspiracy Theories & Magical Thinking
2023/02/04
This week the hosts dive into the intersection between conspiracy theories and the occult, all the way from the wacky to the outright terrifying. This episode explores the basis of the psychological concept ‘magical thinking’ and how it relates to spirituality, as well as how this mode of thinking might help or hinder one’s practice. It also features a discussion on why conspiracy theories are unfortunately so prevalent in the occult world, how to spot them, and the potential dangers they pose if left unchallenged.

Episode 48: Sustainability in Practice
2023/01/15
In this episode, the hosts explore the crossover between spirituality and sustainability. What does it mean to build an environmentally sustainable spiritual practice? How have environmentalism and spirituality historically crossed paths? And why DO people keep burying jars, anyway? Join us this week for a topic very close to our hearts.

Episode 45: Trees!
2022/07/24
It's another Fel and Han special today, with the hosts discussing a subject very dear to our collective hearts: Trees! In this episode, the hosts discuss how seemingly universal tree-lore is and why so many themes might be shared across cultures. We also explore the science behind how trees 'talk' to one another and how this fascinating phenomenon might translate to a spiritual context. Finally, prepare yourself for chaos as we test the definition of hedge witchcraft to its limit. hope you enjoyed us branching out this episode.
For this episode, we drew heavily upon the books Finding The Mother Tree by Suzanne Simard and The Hidden Life of Trees by Peter Wohlleben for our research.
