The ancients had discovered that you could turn a dream into a method to perceive other reality. In practice the reality we live in is given by our stability to perceive this world since birth. In the dream, this mode becomes loose and you can ridirezionarla to perceive other dimensions and the energy structure of the universe.
How do you? Simple, We must as usual to create a habit. We humans cannot create through mere thought, private thing to our Creator, We first need to fix something in time and then realize it thanks to a habit.
Remember then that repeating an action many times over time, the aim wanted to start slowly to materialize. Like a brick on top of each other creates a home.
If every time you go to sleep early to hear the first pictures that you get while sleep comes you become aware of when you start dreaming.
If every time you go to bed before going to sleep you tell yourself you want to see your hands in a dream, sooner or later you'll see.
This repetition with time it becomes a habit until it really happens and then you're asleep and you're also aware of being in your dream.
In a dream you are energy so if you can become aware in your dreams, you no longer have the limitations of a material world but you can try new possibilities.
For example, try prepare some questions before bedtime and sooner or later you will receive the answer.
