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

Key Points

This research proposes that lucid dreaming represents a unique dual-coherence state with distinct neural patterns.
Utilized the BCT Superfluid Lattice Model to define the dual-coherence ratio R = P(f_J)/P(δ).
Investigated EEG findings related to delta-band reduction in lucid REM versus normal REM and NREM.
Identified the DREAM database for further testing of hypotheses.
The dual-coherence ratio R is highest during lucid REM, lower in normal REM, and lowest in NREM.
Validated the previous EEG finding of delta reduction in verified lucid REM by Baird et al. 2019.

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 fJ = 0. 08979 Hz) AND maintenance of local self-referential coherence above the Ncollapse = 1/α₀ = 135 threshold. We define the BCT dual-coherence ratio R = P (fJ) /P (δ) where P (fJ) 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.
