Terminal lucidity is the phenomenon of sudden, heightened mental clarity when on the verge of death

Brain activity goes into overdrive around the point of death

Recent studies suggest increased electrical activity in the brain during and after clinical death could be responsible for near-death experiences.

The benefits of lucid dreaming
