Tree Carr is a
dream worker, TEDx speaker, and the author of nine publications, whose work spans the thresholds of death, dreams, and consciousness.
A transpersonal psychologist with a focus on
altered states, dreamwork, and psychedelic-assisted therapy, Tree is a graduate of the
Alef Trust and a CPD Crossfields Institute Certified Death Doula. She teaches at the College of Psychic Studies, The Psychedelic Society UK, and has tutored
lucid dreaming at the Royal College of Art.
In the 20th episode of
In & Through, host Dr Simon Ruffell and Tree explore the numinous beginnings of Tree’s journey into these liminalities, initiated by a
near-death experience at the age of four, a pivotal moment that shaped her lifelong orientation toward
liminal states and unseen worlds.
This conversation then explores Tree’s work as a death doula, the specificities of supporting people at the end of life, and how death work is inseparable from questions of meaning, presence, and consciousness. They explore dreams as vital explorations of consciousness, discussing why dreaming has held such importance across Indigenous cultures worldwide, and why reconnecting with the dreamscape is especially necessary in the contemporary Western world.
The episode also unpacks the concept of the tem “witch” as a practitioner of magic, wisdom, and embodied knowledge, and why reclaiming and redefining this term matters as magic begins to reawaken in the British Isles. Looking toward the future, Simon and Tree also discuss AI and its role in the evolution of consciousness, debating whether it could be a powerful tool for good or ill, depending on human intention. This episode concludes with reflections on interconnectedness, integrity, and the importance of hope in the face of global challenges.
