Double dissociation in EEG microstates during dreaming experience vs. no experience. (A) The five EEG microstates identified by k-means cluster analysis across participants in two conditions (dreaming experience, DE and no experience, NE). (B) The mean and standard error of the global explained variance (GEV) of each microstate in both conditions. Microstate 3 explained significantly more variance in the conscious experience condition (DE), while microstate 4 explained significantly more variance in the no conscious experience condition (NE). (C) Mean power in the delta frequency band for microstate 3 and microstate 4 in DE and NE. Delta power decreases significantly when dreams are recalled for both microstates (for details of all microstates see Suppl. Fig. S2). (***p < 0.0001).
