“…Regarding the function of dissociative thought, it seems to be accompanied by a down-regulation of negative emotion in dreaming as well as in psychiatric disorders ( LaBerge and Rheingold, 1991 ; Phillips et al, 2001 ; Voss et al, 2013 ; Gackenbach and Bosveld, 2014 ). Several studies show lucidity in dreams to be associated with positive rather than with negative emotions ( LaBerge and Rheingold, 1991 ; Voss et al, 2013 ; Gackenbach and Bosveld, 2014 ), albeit most studies do not differentiate between positive feelings during the dream vs. positive feelings following awakening from a lucid dream. It is our observation (Voss et al, unpublished) that dreamers often experience their lucid dreams to be emotionally neutral, sometimes accompanied by a sense of achievement (“I did it!” and “success!”) and euphoria after awakening, both instances falling under the category of what Lewis (1995) refers to as “self-conscious emotion.” Self-conscious emotions such as guilt, shame, or empathy require the ability to reflect on the self and, therewith, frontal lobe as well as anterior insular cortex (AIC) activity ( Gu et al, 2013 ).…”
