Lucid dreaming was proven real in 1981, when a sleeping subject signaled to a lab with pre-agreed eye movements. Four decades later we can hold a two-way conversation with a dreamer. A map of what's settled, what's suggestive, and what's still unknown.

The landmark papers, grouped and annotated: the 1981 eye-signal proof, the neurophysiology of the lucid state, the induction trials, the application studies, and the 2021 two-way dialogue. Every entry with a real citation and DOI.

When a dream becomes lucid, the brain changes measurably: frontal gamma rises, and prefrontal regions that REM normally switches off come back online. Stimulate that frontal gamma and you can nudge lucidity into being. What the neural correlates actually show, from a handful of small but pointed studies.

The honest frontier. We still can't induce lucidity reliably, don't fully know why the prefrontal cortex switches back on, and know little about long-term effects. The unsolved problems, why they're hard, and what would move each one forward.
