Lucid dreaming is when you become aware that you are dreaming in your dream... nothing very special till here though... Things get interesting when you get practice and can start controlling a vivid dream...you can choose what happens in your dreams, and change anything you don't like. Benefits - there are so many... To begin with lemme tell you a lot of great scientists come up with ideas and solve problems in lucid dreams...Nicola Tesla, Issac Newton, Einstein were all lucid dreamers...they solved equations and invented things with the help of lucid dreaming... Basically, when you dream you have full access to your subconscious mind...which is actually 95% of your mind, way more powerful than the conscious. And when you access it you can choose to change some of your beliefs, habits...or even manifest situations and events in real life...or just have fun - it's better than any 4D or VR movie action thriller or whatever you like......
