BCT Letter 252: Dreams as OHC Ground-State Relaxation — A BCT Framework and Preliminary EEG Evidence

We propose that dreaming corresponds to relaxation of the biological condensate toward the OHC ground state during REM sleep, with reduced sensory coupling. The BCT Superfluid Lattice Model predicts enhanced infra-slow spectral power at the OHC Josephson frequency f_J = ω_J/2π = 1/(2π√π) = 0.08979 Hz during REM vs NREM sleep. This is a locked BCT result from ω_J² = 1/π, not a free parameter. Period T_J = 11.14 seconds, upper edge of the infra-slow oscillation band. Tested on real EEG data from the Sleep-EDF Expanded database (PhysioNet, DOI: 10.13026/C2X676), n=5 subjects, 863 REM epochs, 2462 N2 epochs, 530 N3 epochs. REM shows elevated power near f_J vs N2 (ratio 1.19, t=3.285, p=0.001). The N3 comparison is inconclusive (p=0.087, high variance). Wake infra-slow power is highest, consistent with known waking ISO oscillations. Results are directionally consistent with the BCT prediction. Replication with larger samples required.
