“…Two other classes of phenomenal states presenting direct empirical counterexamples to AST are, first, all states of complete "ego-dissolution" (Metzinger & Millière, 2020), as for example caused by the administration of fast-acting serotonergic psychedelic drugs like N,N-dimethyltryptamine (DMT) and 5-methoxy-N, N-dimethyltryptamine (5-MeO-DMT) (Lebedev et al, 2015;Letheby, 2020;Millière, 2017;Millière, Carhart-Harris, Roseman, Trautwein, & Berkovich-Ohana, 2018;Nour & Carhart-Harris, 2017). Second, any phenomenological markers of attention or an attentional schema also seem to be absent in certain episodes of conscious experience which can occur during NREM-sleep (Windt, Nielsen, & Thompson, 2016) and which have provisionally been termed "lucid dreamless sleep" (Metzinger, 2019;Thompson, 2015;Windt, 2015b).…”
