Study Links Out-of-Body Experiences to Brain States Between Sleep and Waking

Scientists have found that out-of-body experiences and other unusual bodily perceptions may occur when brain activity blends features of both sleeping and waking states, according to a new study. Researchers at Radboud University in the Netherlands monitored 35 participants using EEG caps during meditation, sleep, and sleep arousals. Twenty reported 36 unusual experiences, including floating, paralysis, and leaving their bodies, which correlated with decreased delta and theta waves and increased beta and gamma activity, particularly in temporal brain regions. The findings suggest these experiences arise from blurred boundaries between consciousness states, not specific sleep stages. This could explain sleep paralysis hallucinations and may offer insights into how the brain anchors our sense of being inside our bodies, though further research is needed.
