Lucid Dreaming Brain Network Based on Tholey's 7 Klartraum Criteria.

Lucid dreaming is a state where dreamers know they are dreaming and can deliberately control the dream's content. This study examined seven awareness criteria of lucid dreaming, originally proposed by Paul Tholey, and mapped each to its underlying brain circuits. The results showed that multiple brain regions are involved, and during lucid dreaming a coordinated brain network emerges that is more than the sum of its parts. The findings suggest that lucid dreaming involves a distributed neural network rather than a single area, though further research is needed to fully understand the neurological basis.

Abstract

Lucid dreaming refers to a dream state characterized by the dreamers' awareness of being in a dream and being able to volitionally control its content. The aim of this study was to describe and model neurophysiological evidence for the seven awareness criteria of lucid dreaming based on those proposed by Paul Tholey. Each of the awareness criteria was analyzed separately with regard to its underlying neurocircuits. We hypothesized that not one, but several regions are involved in the state of lucid dreaming. Our results have shown a satisfactory overlap of the awareness criteria and the brain regions activated. During lucid dreaming, a brain network seems to emerge, that is something other than the sum of its parts. Further research is needed to understand the psychoneurological underpinnings of lucid dreams.
