Nothingness Is All There Is: An Exploration of Objectless Awareness During Sleep

Recent years have seen a heightened focus on the study of minimal forms of awareness during sleep to advance the study of consciousness and understand what makes a state conscious. This focus draws on an increased interest in anecdotical descriptions made by classic Indian philosophical traditions about unusual forms of awareness during sleep. For instance, in the so-called state of witnessing-sleep or luminosity sleep, one is said to reach a state that goes beyond ordinary dreaming and abide in a state of just awareness, a state in which one is not aware of anything else other than one's own awareness. Moreover, for these traditions, this state is taken to be the essence or background of consciousness. Reports on such a state opens the door to exciting new lines of research in the study of consciousness, such as inquiry into the so-called objectless awareness during sleep-states of awareness that lack an ordinary object of awareness. In this two-staged research project, we attempted to find the phenomenological blueprints of such forms of awareness during sleep in 18 participants by conducting phenomenological interviews, informed by a novel tool in qualitative research, the micro-phenomenological interview (MPI) method. Following a phenomenological analysis, we isolated a similar phase across 12 reported experiences labeled as nothingness phase since it described what participants took to be an experience of nothingness. This common phase was characterized by minimal sense of self-a bodiless self, yet experienced as being somewhere-, the presence of non-modal sensations, relatively pleasant emotions, an absence of visual experience, wide and unfocused attention, and an awareness of the state as it unfolded.

Automated summary

In recent years, there has been increased interest in studying minimal forms of awareness during sleep to advance the understanding of consciousness. This interest is inspired by the descriptions of unusual forms of awareness during sleep in classic Indian philosophical traditions. Through phenomenological interviews and the micro-phenomenological interview method, a common phase labeled as the "nothingness phase" was identified, characterized by minimal sense of self, non-modal sensations, pleasant emotions, absence of visual experience, wide and unfocused attention, and awareness of the unfolding state.
