Seeing brilliant lights during near-death experiences may arise from a surge of bioluminescent biophotons in the brain when blood flow returns after oxygen deprivation. The authors propose that reperfusion triggers an overproduction of free radicals and excited molecules, leading to a transient increase in biophoton emission within retinotopic visual areas. If this emission exceeds a threshold, the brain interprets the intrinsic photons as external light, creating the perception of brilliant lights. The article reviews experimental studies that support this concept and links the idea to phosphenes, dream-like imagery during REM sleep, and self-consciousness possibly involving low-energy quantum entanglements. It is presented as a discussion piece, not a definitive explanation.
