Experiences that become meaningful to the self involve synchronous activity in a paralimbic network of self-awareness and dopaminergic activity, including medial prefrontal and medial parietal/posterior cingulate cortices. Oral administration of 100 mg dopamine improved noetic (conscious) metacognition in minimal self-awareness. In a separate experiment with extended self-awareness, dopamine improved retrieval accuracy of memories of self-judgment (autonoetic metacognition). Magnetoencephalography showed increased power of oscillations preferentially in the medial prefrontal cortex, explaining dopamine's specific effect on explicit self-awareness and autonoetic metacognition.

The scope of unconscious processing remains hotly debated, driven by diverse methods for manipulating and measuring perceptual awareness. Through dialogue among researchers with varied theoretical backgrounds, ten recommendations and nine outstanding issues are provided for designing experimental paradigms, analyzing data, and reporting results. These guidelines aim to evoke discussion about norms in studying unconscious processes and help researchers make informed decisions. While some recommendations may not align with existing approaches and will likely evolve, they are intended to foster a more convergent understanding of the extent and limits of unconscious processing.

Nightmares are less frequent and less distressing for people who practice mindful acceptance—the ability to experience thoughts and feelings without judgment—rather than merely mindful presence, or paying attention to the present moment. Two studies, one with 338 participants and another with 187 frequent lucid dreamers who used meditation and lucid dream induction techniques, found that acceptance was more strongly linked to fewer nightmares and less nightmare distress than presence. People with high meditation expertise and practice of lucid dreaming techniques reported the lowest nightmare frequency. Among frequent lucid dreamers, more lucid dreaming was associated with higher mindfulness. The findings suggest that the two facets of mindfulness play distinct roles in dream quality, with potential clinical applications.
