In my opinion everyone should learn how to get a lucid dream not only once but regularly. This is a powerful mental tool and using it can open up another world that can help everyone in different ways! The benefits of this I think could actually help a lot of people with their daily lives.
You Can Increase Your Creativity...Dreams reveal our most creative side because of the free-flow of ideas arising from the subconscious mind, unhindered by the rational conscious mind.
There are many instances where lucid dreaming has helped increase creativity whether it be to help the author of alice in wonderland write his book or help composers like Mozart come up with amazing music and even help painters such as William Blake come up with masterpieces!
Going into a lucid state can increase your creativity and whatever you picture you can bring back with you into the physical world.
