Our waking life expectations and firm beliefs of how the world functions limits what we experience in the dream world. We imagine ideas of how we understand things function. We look at things and think, this is this, this is what it does and how it works. The world as we see it is filtered through a grid of thought. So just as we expect things to be that way in waking life. It also can mean that our dreams follow very similar patterns. Many people become frustrated with boring dreams. They want to experience what is impossible in the physical world, but their minds are imprisoned to the way they think.
You must break your expectations. Break boring dull habits. Expectations of how things are. Let your imagination run wild!
When you break down your habit of having ideas of how things work, your mind can run wild. Dream control comes with ease when you know anything is possible with the push of your will. While the expectations of the waking world imprison you and limit your ability to have control outside of what you are used to doing in waking life.
