Overlap with DMT and Altered States

Threshold Contact and Sleep Paralysis with Sheila Pryce Brooks

Dr. Sheila Pryce Brooks received her doctoral degree from the University of York in the United Kingdom, where her dissertation examined the phenomenology of sleep paralysis. Her ongoing research explores Threshold Contact Experiences, bridging science, spirituality, and the paranormal. Dr. Brooks lives and works in Jamaica, offering unique insight as both an experiencer and scholar.

She discusses the phenomenology of sleep paralysis and how it can evolve into what she terms Threshold Contact Experiences. Drawing on both personal and academic research, she explains the transition from terror to empowerment and describes encounters with nonhuman intelligences. Her discussion explores the intersections between sleep states, consciousness, folklore, and transpersonal experience.
