Once you have a firm grasp on the core foundational exercises (Keeping A Dream Journal, Preparations For Lucid Dreaming, and Tips To Optimize Your Sleep) and have successfully initiated several lucid dreams through one of the various lucid dreaming techniques, then it’s time to learn how to control your dreams.
Beliefs and Expectations
The key to all dream control is beliefs and expectations. The only thing limiting you from doing amazing things in your dreams are your own self-limiting beliefs.
Basically, our dreams are created from our lifetime of knowledge, experience and expectations. We have been taught, programmed and perceived how the 3-dimensional world operates, such as societal rules, gravity and other laws of physics.
However, the rules of gravity and societal rules no longer apply in the dream world. We are free to do things that are impossible in our waking lives.
Therefore, if you believe you can travel to another universe in a dream, you can!
