Lucid Dreaming — The Complete Guide

A lucid dream is one in which you become aware that you’re dreaming, and often gain the ability to influence what happens. Lucid dreaming is a scientifically documented state, confirmed in sleep labs where lucid dreamers signalled their awareness with pre-agreed eye movements while measurably in REM sleep.

The science of lucid dreaming

Lucid dreams occur during REM sleep, when brain activity is high. Studies show that during lucidity, regions of the prefrontal cortex associated with self-awareness — usually quiet in normal dreams — become active. This blend of dreaming and self-reflection is what makes lucidity possible.
