I was just curious, before I ever had a lucid dream but had heard about the concept, I couldn't comprehend how it was possible to be dreaming but still be conscious.. I thought, wouldn't you just wake up if you became conscious? How is it possible to be sleeping and dreaming but conscious and aware without waking up? I've had many lucid dreams now but still don't understand how it works.. does anyone know or have any ideas? The human brain sure is mysterious.
