Dan Marshall is a sleep content creator and audio producer specialising in the science of consciousness, dreams, and brainwave entrainment. Through his project Nocturnal Mind, Dan creates long-form guided sleep experiences and documentary audio designed to help listeners understand and work with their sleeping minds rather than simply switch off for the night. Drawing on peer-reviewed sleep science and decades of research into lucid dreaming, REM neuroscience, and auditory brainwave entrainment, Dan produces content that bridges the gap between accessible storytelling and genuine scientific grounding. His recordings are built for people who want more from sleep — deeper rest, richer dreams, and the occasional extraordinary experience of waking up inside one. Dan is based in New Zealand and publishes through Nocturnal Mind and Brainwave Lab.
