Lucid dreaming verified by volitional communication during REM sleep
Stephen LaBerge, Lynn E. Nagel, et al. · 1981 · Perceptual and Motor Skills, 52(3), 727-732
Summary
Classic sleep-laboratory study in which lucid dreamers used prearranged eye-movement signals to communicate awareness from REM sleep.
Why it matters here
Supports the reality of lucid dreaming as a measurable state while leaving spiritual interpretations of dream travel or insight as separate claims.
Linked claims
An interpretive overlay on OBE, positing literal travel through 'astral' space. No controlled evidence beyond the OBE phenomenon itself.
Lucid dreaming is established. Tibetan Dream Yoga and Western traditions claim it accesses something more.
