The Science of Lucid Dreaming

What if you could flip a switch and wake up inside your own dreams? In a normal dream,

we usually just accept the most bizarre situations without question—scientists call this "delusional

thought". But in a lucid dream, the brain’s logical centre, the dorsolateral

prefrontal cortex, suddenly fires up. Researchers have actually measured this as a surge

in 40-Hz gamma waves—a type of brain activity usually seen when we’re wide awake and focusing.

This turns the dream into a hybrid state: you have all the vivid imagery of sleep,

but the "higher-order" awareness of being awake. It’s so objective that scientists

can even verify it in a lab by having sleepers move their eyes in a specific "left-right" pattern
