Exploring the Mind Through Liminal Dreaming
With Jennifer Dumpert and Adam Haar Horowitz
August 14 - 16, 2026
We’re all natural liminal dreamers. Every 24 hours, in the spaces between waking and sleep, we pass through the zones of liminal dreaming, hypnagogia and hypnopompia, where the mind meanders between daytime awareness and the depths of the dream.
Every one of us possesses the ability to maintain the crisp awareness of the waking mind while sinking into the free-associative, kaleidoscopic realms of the unconscious. It’s easy to learn to locate and linger in this unique realm of consciousness — and to plumb it for creativity, problem-solving, mental and spiritual healing, and consciousness exploration.
This workshop provides an in-depth exploration of hypnagogia and hypnopompia, integrating pioneering neuroscience with deep experiential practice. Jennifer Dumpert, author of Liminal Dreaming: Exploring Consciousness at the Edges of Sleep, draws on decades of work developing and teaching practices for accessing these remarkable states. Adam Haar Horowitz, neuroscientist and co-inventor of Targeted Dream Incubation (TDI) and the Dormio device, presents the underlying neurophysiology of sleep onset and demonstrates how real-time sleep sensing and precisely timed auditory cues can stabilize and extend hypnagogia.
Together, Jennifer and Adam bridge empirical and contemplative approaches, guiding participants to not only experience liminal dreaming firsthand but to understand its measurable mechanisms and transformative potentials.
Note: As we will be settling into a dreamy state throughout the weekend, you are encouraged to bring any comforting items that might assist you in relaxing: special pillow, eye mask, blanket, etc.
