Lucid Dreaming Is A Powerful Tool
It takes practice, but in a lucid dream state you are aware that you are dreaming and in that awareness you have to ability to control to scope and the details even the subject matter. I can direct my dreams like a motion picture. I have been able to give myself superpowers, travel across the universe as well as turn a nightmare into an adventure. It takes practice and discipline, but I've taught others to do this and had very good results I have even been able to solve problems that were vexing me in real life and apply the soltuion when awake - as long as the solution didn't require superpowers of course. I learned how to do higher math better while asleep. I have invented books and read them while dreaming. It is truly amazing
It usually takes about a month or more to start actually lucid dreaming. But it is worth the effort.
Lucid dreaming unbinds your mind from the limitation you yourself build in and once you learn you will find that many of the limitations you have in life are really just constructs and not realy limitations.
