Alpha oscillations, a hallmark of waking visual perception when eyes close, do not reliably increase during lucid dreams when dreamers signal that their dream-eyes are closed. In 150 signals from 11 lucid dreamers, dream-eye closure was associated with fading visual content only about half the time. In three participants where visual content presence versus absence could be compared, increased alpha power accompanied momentary lack of visual content. Real-time reporting via sniffing patterns enables dynamic investigation of dream perception.
