I certainly have not been enlightened and been able to let go of my ego entirely... Besides even Buddhists say that you will enter back into your own self afterwards. What can I say, I like to have fun, im just a kid. However, I think that lucid dreaming gives great insight into your subconscious and can be used as a tool for developing higher knowledge. As a former disbeliever in all spiritual aspects I only take in what i think applies to my life in the present moment. What is the point of avoiding living this life, I will let my spiritual self take its course when its time comes... its a long life, stuff is fun! There is time for eternal peace and happiness later, and i will only be able to put all my thoughts and efforts into seeking that when i am ready to.
