BCT Letter 253: Lucid Dreaming as BCT Dual-Coherence — The Simultaneous OHC and N_collapse State

Lucid dreaming is described as a distinct dual-coherence state in the BCT Superfluid Lattice Model, characterized by simultaneous enhanced infra-slow power near a Josephson frequency of 0.08979 Hz and maintenance of local self-referential coherence above a threshold of 135. The model defines a dual-coherence ratio comparing power at the Josephson frequency to delta-band power, predicting this ratio is highest in lucid REM, lower in normal REM, and lowest in NREM. This prediction aligns with a replicated EEG finding of delta reduction during verified lucid REM. The DREAM database is identified as the appropriate dataset for testing, and the prediction has zero free parameters.

Abstract

Lucid dreaming is proposed as a qualitatively distinct dual-coherence state within the BCT Superfluid Lattice Model: simultaneous elevation of OHC Josephson coupling (enhanced infra-slow power near f_J = 0.08979 Hz) AND maintenance of local self-referential coherence above the N_collapse = 1/α₀ = 135 threshold. We define the BCT dual-coherence ratio R = P(f_J)/P(δ) where P(f_J) is power near the Josephson frequency and P(δ) is delta-band (0.5–4 Hz) power. BCT predicts R is highest in lucid REM, lower in normal REM, and lowest in NREM. This is consistent with the one robustly replicated EEG finding in the lucid dreaming literature: delta reduction during verified lucid REM (Baird et al. 2019). The DREAM database (Wong et al., Nature Communications 2025, DOI: 10.1038/s41467-025-61945-1) is identified as the appropriate dataset for testing.
