Lucid-dreaming eye-signal experiments by Stephen LaBerge

Record summary

Stephen LaBerge and colleagues demonstrated that some dreamers could recognize lucid dreams during REM sleep and signal prearranged eye movements to researchers. The work provided an unusually direct bridge between subjective dream awareness and physiological recording, making it valuable for comparing consciousness reports with external markers. It also helped distinguish lucid dreaming from ordinary dream recall or retrospective reconstruction. Uncertainty concerns the small number of highly trained participants, selective successful trials and the interpretation of physiological signatures. The findings do not establish paranormal perception, but they are foundational for altered-state research.
